## Chapter – 4

__Sequence and Series__

We have already discussed about sequence and series in grade XI. So, here we discuss about the natural numbers and the sum of the natural numbers and also about the principle of mathematical induction.

Class 12 Sequence and Series chapter has 2 exercises in total. You can click on the buttons given below to view exercise-wise notes.

### Natural Number

The numbers 1, 2, 3, … are said to be the natural numbers. Now we derive some of the formulae for the sum of the first n natural numbers, the sum of the squares of first n natural numbers and the sum of the cubes of first n natural numbers.

## Introduction to Sequence and Series

Sequences and series are fundamental concepts in mathematics that deal with ordered lists of numbers and the sum of these numbers, respectively. A sequence is an ordered list of numbers following a specific pattern or rule, while a series is the sum of the terms in a sequence. These concepts are widely used in various branches of mathematics, including calculus, algebra, and number theory.

### Sequence

A sequence is an ordered list of numbers arranged according to a specific rule or pattern. Each number in the sequence is called a term. For example, \(1, 4, 7, 10, …\), represents a sequence where each term increases by 3.

### Series

A series is the sum of the terms in a sequence. It is represented by adding all the terms in the sequence. For example, the series \(1 + 4 + 7 + 10 + …\) would be the sum of all terms in the given sequence.
