Solutions of Chapter 8 Sequences and Series of Class 11 NCERT book available free. All exercise questions, examples, miscellaneous are done step by step with detailed explanation for your understanding.

In this Chapter we learn about Sequences

Sequence is any group of numbers with some pattern.

Like 2, 4, 8, 16, 32, 64, 128, 256, ....

1, 2, 3, 4, 5, 6, 7, 8

In this chapter we learn

What a sequence is - and what is finite, infinite sequence, terms of a sequence
What a series is - it is the sum of a sequence
Denoting Sum by sigma Σ, and what it means
What is an AP (Arithmetic Progression) is, and finding its n^th term and sum
Inserting AP between two numbers
What is Arithmetic Mean (AM), and how to find it
What is a GP (Geometric Progression) is, and finding its n^th term and sum
Inserting GP between two numbers
What is Geometric Mean (GM), and how to find it
Relationship between AM and GM
Sum of special series
Finding sum of series when n^th term is given
Finding sum of series when n^th term is not given
