(Back to the College Algebra Homepage) College Algebra Tutorial 54C: Arithmetic Sequences and Series Learning Objectives After completing this tutorial, you should be able to: Know what an arithmetic sequence is. Find the n th term of an arithmetic sequence. Write the formula for the nth term of an arithmetic sequence. Calculate an arithmetic series. Introduction In this tutorial we will mainly be going over arithmetic sequences and series. We will be going forwards and backwards with this. First we will be given the formula for the n th term and we will be finding specified terms. Then we will turn it around and look at the terms and find the formula for the n th term. We will finish up by looking at arithmetic series. If you need a review on sequences, feel free to go to Tutorial 54A: Sequences . If you need a review on sequences, feel free to go to Tutorial 54B: Series . I think that you are ready to move ahead. Tutorial Arithmetic Sequence An arithmetic sequence is a sequence such that each successive term is obtained from the previous term by addition or subtraction of a fixed number called a common difference. The sequence 4, 7, 10, 13, 16, ... is an example of an arithmetic sequence. The pattern is that we are always adding a fixed number of three to the previous term to get to the next term.

Algebra Applied Mathematics Calculus and Analysis Discrete Mathematics ... Interactive Demonstrations Arithmetic Mean The arithmetic mean of a set of values is the quantity commonly called "the" mean or the average. Given a set of samples , the arithmetic mean is It can be computed in Mathematica using Mean list The arithmetic mean is the special case of the power mean and is one of the Pythagorean means When viewed as an estimator for the mean of the underlying distribution (known as the population mean ), the arithmetic mean of a sample is called the sample mean For a continuous distribution function , the arithmetic mean of the population, denoted , or and called the population mean of the distribution, is given by where is the expectation value . Similarly, for a discrete distribution The arithmetic mean satisfies and if and are independent statistics . The "sample mean," which is the mean estimated from a statistical sample, is an unbiased estimator for the population mean. Hoehn and Niven (1985) show that for any constant . For positive arguments, the arithmetic mean satisfies

70. Modular Arithmetic — An Introduction Modular arithmetic lets us state these results quite precisely, and it also provides a convenient language for similar but slightly more complex statements. http://www.math.rutgers.edu/~erowland/modulararithmetic.html

header("Modular Arithmetic"); Modular arithmetic is quite a useful tool in number theory. In particular, it can be used to obtain information about the solutions (or lack thereof) of a specific equation. This page gives a fairly detailed introduction. Another good introduction, in the form of an interactive tutorial, can be found in Part 2 of Math Alive: Cryptography Contents I. An Introductory Example II. Definition and Further Examples III. Properties of Congruence IV. Exercises I. An Introductory Example Everyone knows that set of integers can be broken up into the following two classes: There are certain generalizations we can make about the arithmetic of numbers based on which of these two classes they come from. For example, we know that the sum of two even numbers is even. The sum of an even number and an odd number is odd. The sum of two odd numbers is even. The product of two even numbers is even, etc. Modular arithmetic lets us state these results quite precisely, and it also provides a convenient language for similar but slightly more complex statements. In the above example, our modulus is the number 2. The modulus can be thought of as the number of classes that we have broken the integers up into. It is also the difference between any two "consecutive" numbers in a given class.

The Egyptian Zero Egyptian Counting Addition Subtraction ... Egyptian Fractions EYPTIAN COUNTING WITH HEIROGLYPHS These are the basic glyphs (symbols) used in Egypt for counting over 4000 years ago: Writing an integer consists of writing the number (from to 9) of the proper symbols to represent the integer. Thus, There is also a glyph which can translated as "equals" and a compact way of writing large glyphs, as shown below on the right, for two ways 35: in early Egypt Addition and subtraction were simple processes using the counting glyphs . To add two numbers, collect all symbols of similar type and replace a ten of one type by one of the next higher order. For example, adding 35 and 17: add Subtraction is a reversal of the process, if necessary replace a higher, so subtract Multiplication and Division Multiplication and Division were also simple processes using the counting glyphs . To multiply two numbers, all you needed to understand was the double or the half of an integer; i.e., the 2 times table.

Matrix arithmetic operations are defined by the rules of linear algebra. Array arithmetic operations are carried out element by element, and can be used with multidimensional arrays. The period character ( ) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs and are not used. Addition or unary plus. A+B adds A and B A and B must have the same size, unless one is a scalar. A scalar can be added to a matrix of any size. Subtraction or unary minus.

78. Date Arithmetic Worksheet formulas for doing arithmetic operations on Dates and Times in Microsoft Excel. http://www.cpearson.com/excel/datearith.htm

Date Arithmetic If you're writing an application that works with dates And times in Excel, you'll probably be doing some sort of arithmetic operations with those dates. This page explains several formulas that you may find useful. Adding Dates You can add some number of days to a date by simply using the =SUM function. Since Excel stores dates as a number of days, no further work is required. For example, to add 5 days to 1/1/98, in , use which gives 1/6/98. To add a number of months or years to a date, you first need to decompose the initial date into its year, month, and day components, add in the desired offset, and then have Excel put the components back together. For example, say you have a date in , to which you want to add 3 months and 4 days. You'd use the following formula: =DATE(YEAR(A1), MONTH(A1)+3, DAY(A1)+4) Excel will automatically handle the situation which arises when you pass a number greater than 12 to the MONTH function, or a number greater than 31 to the DAY function.

Navigation index modules next previous ... The Python Tutorial 14. Floating Point Arithmetic: Issues and Limitations Floating-point numbers are represented in computer hardware as base 2 (binary) fractions. For example, the decimal fraction has value 1/10 + 2/100 + 5/1000, and in the same way the binary fraction has value 0/2 + 0/4 + 1/8. These two fractions have identical values, the only real difference being that the first is written in base 10 fractional notation, and the second in base 2. Unfortunately, most decimal fractions cannot be represented exactly as binary fractions. A consequence is that, in general, the decimal floating-point numbers you enter are only approximated by the binary floating-point numbers actually stored in the machine. The problem is easier to understand at first in base 10. Consider the fraction 1/3. You can approximate that as a base 10 fraction: or, better, or, better, Stop at any finite number of bits, and you get an approximation. On a typical machine running Python, there are 53 bits of precision available for a Python float, so the value stored internally when you enter the decimal number is the binary fraction which is close to, but not exactly equal to, 1/10.
