Document Summary

A sequence is a real-valued function f whose domain is the set positive integers (n). The numbers f(1), f(2), are called the terms of the sequence. Notation function notation vs subscript notation: f(1) s1, f(2) s2, , f(n) sn, . In discussing sequences the subscript notation is much more common than functional notation. We"ll use subscript notation throughout our treatment of analysis. Specifying a sequence there are several ways to specify a sequence: by giving the function. For example: (a) sn = (b) sn = n(cid:27). This is the sequence {1, or {sn} =(cid:26) 1. This is the sequence { 1, 4, 9, 16, . , ( 1)nn2, : by giving the rst few terms to establish a pattern, leaving it to you to nd the function. This is risky it might not be easy to recognize the pattern and/or you can be misled. (a) {sn} = {0, 1, 0, 1, 0, 1, .
