Mathematics Sequences And Series A student who has mastered the chapter sequences and series of class 11 would also have a strong hold on the concepts related to the chapter, namely sequence and series, arithmetic progression (a. p.), arithmetic mean (a.m.), geometric progression (g.p.), general term of a g.p., the sum of n terms of a g.p., infinite g.p. and its sum, geometric. Chapter 8 class 11 sequences and series.

A sequence in which the difference of two consecutive terms is constant, is called arithmetic progression (ap). properties of arithmetic progression (ap) if a sequence is an a.p. then its nth term is a linear expression in n i.e. its nth term is given by an b, where a and s are constant and a is common difference. Sequence and series 149 9.1.2 a geometric progression (g.p.) is a sequence in which each term except the first is obtained by multiplying the previous term by a non zero constant called the common ratio. let us consider a g .p. with first non zero term a and common ratio r, i.e., a, ar, ar2, , arn – 1, here, common ratio r = –1 –2.
