Mathematics can be both fantastic and challenging at the same time. Specially in class 10 when students have to give board paper. So our NCERT class 10 Mathematics Chapter 5 Arithmetic Progressions notes will provide conceptual clarity to the students. It will work like a bridge for students between class room theory lecture and solving exercise at home.
These Class 10 Chapter 5 Arithmetic Progressions Notes is a masterstroke for students who want to pursue a career in science, like becoming an engineer, scientist etc. Most of the concept given in class 11 maths have already been introduced in class 10 maths. So these notes are also the foundation of class 11 math.

Below we have also given most important topics of NCERT Class 10 Mathematics chapter 5 Arithmetic Progressions Notes. Students should revise these notes regularly to remember the chapter properly.
Important Topics of Arithmetic Progressions
1. What is a Sequence?
- A sequence is an arrangement of numbers in a definite order according to some rule.
- The various numbers occurring in a sequence are called its terms.
- We denote the terms of a sequence by a_1, a_2, a_3…etc. Here, the subscripts denote the positions of the terms in the sequence.
- In general, the number at the nth place is called the nth term of the sequence and is denoted by a_n. The nth term is also called the general term of the sequence.
- A sequence having a finite number of terms is called a finite sequence.
- A sequence which do not have a last term and which extends indefinitely is known as an infinite sequence.
