Consider the following examples:
Assume that there is a generation gap of 30 years and we are asked to find the number of ancestors, i.e., parents, grandparents, great grandparents, etc. that a person might have over 300 years. The total number of generations= 300/30=10. The number of a person’s ancestors for the first, second, third, tenth generations are 2,4,8,16,32,…,1024. These numbers form what we call a sequence.
According to the CBSE NCERT Class 11 Maths Chapter 9, consider the successive quotients that we obtain in the division of 10 by 3 at different steps of division. In this process we get 3,3.3,3.33,3.333,… and so on. These quotients also form a sequence. The various numbers occurring in a sequence are called its terms.
Apart from these terms, students will also get to know about terms like Geometric Mean, Arithmetic Mean, Arithmetic Progression, Series and the relationship between them. You can download the solutions for NCERT Class 11 Maths Chapter 9 PDF from below. These solutions will instantly help you whenever required.

CBSE Class 11 Maths Chapter 9: Sequences and Series
We denote the terms of a sequence by a1, a2, a3,…,an,…, etc, the subscripts denote the position of the term. The nth term is the number at the nth position of the sequence and is denoted by an. The nth term is also called the general term of the sequence. Thus, the terms of the sequence of a person’s ancestors mentioned above are a1=2, a2=4, a3=8,…, a10=1024.
A sequence containing a finite number of terms is called a finite sequence. For example sequence of ancestors is a finite sequence since it contains 10 terms (a fixed number). CBSE NCERT Class 11 Maths Chapter 9 Sequences and Series further teaches about the infinite sequence. For example, the sequence of successive quotients mentioned above is an infinite sequence, infinite in the sense that it never ends.
