Return to Table of Content     Chapter 1:   SEQUENCE AND SERIES Content Definition. Convergent, divergent, bounded & monotone sequences. Infinite sums: Basics, Convergence and divergence, Tests for convergence for positive term series, Alternating series – Leibnitz test, Absolute convergence, conditional convergence, Convergence of power series.    1.1. Definition: A sequence is a list of numbers  in a given order. Each of   and so on represents a number.These are the terms of the sequence. For example, the sequence 2, 4, 6, 8, 10, 12,…., 2n,…. has first term   second term and n th term     Order is important.  The sequence 2, 4, 6, 8 . . . is not the same as the sequence 4, 2, 6, 8 . . . . The integer n is called the index of , and indicates where   occurs in the list.    Examples     1.2. Convergence and Divergence of Sequence Definition: A sequence which h...
