Class 10 Maths Chapter 5: Arithmetic Progressions
An Arithmetic Progression (AP) is a sequence of numbers in which the difference between any two consecutive terms is constant. This constant difference is called the common difference.
For example:
2, 5, 8, 11, 14, …
Here, the common difference is:
5 − 2 = 3
8 − 5 = 3
Therefore, the common difference is 3.
In Class 10 Maths, students learn how to identify an arithmetic progression, find its common difference, calculate the nth term, and find the sum of the first n terms of an AP.
The chapter also includes several important application-based questions that help students understand how arithmetic progressions can be used to solve real-life mathematical problems.
Let’s now look at the solutions to each exercise.
Exercise 5.1 – Class 10 Maths Arithmetic Progressions
Exercise 5.1 introduces students to the basic concept of Arithmetic Progressions. In this exercise, students learn how to identify whether a given sequence is an AP and find the common difference between consecutive terms.
Understanding the concept of common difference is very important because it forms the foundation for solving the remaining exercises of this chapter. Students should carefully understand how the terms of an arithmetic progression are arranged and how the common difference remains constant.

Exercise 5.2 – Class 10 Maths Arithmetic Progressions
In Exercise 5.2, students move forward and learn how to find the nth term of an Arithmetic Progression. The general formula for finding the nth term is an important concept that students should understand thoroughly.
The formula is:
aₙ = a + (n − 1)d
where:
a = first term of the AP
d = common difference
n = number of terms
aₙ = nth term of the AP
This exercise contains questions that require students to apply the formula correctly and identify the given values carefully. Understanding this exercise will also help students solve many important questions asked in school examinations and CBSE board examinations.

Exercise 5.3 – Class 10 Maths Arithmetic Progressions
Exercise 5.3 focuses on finding the sum of the first n terms of an Arithmetic Progression. This is one of the most important concepts in Chapter 5 and requires students to understand and apply the correct formula.
The formula for finding the sum of the first n terms is:
Sₙ = n/2 [2a + (n − 1)d]
where:
- Sₙ = sum of the first n terms
- n = number of terms
- a = first term
- d = common difference
Students should pay special attention to identifying the first term, common difference, and number of terms before substituting values in the formula.

Exercise 5.4 – Class 10 Maths Arithmetic Progressions
Exercise 5.4 helps students apply the concepts of Arithmetic Progressions to different mathematical and real-life situations. The questions may require students to use concepts such as the nth term and the sum of the first n terms of an AP.
This exercise is particularly useful for developing problem-solving skills because students need to carefully understand the information given in each question before selecting the appropriate formula.
Before solving these questions, make sure that you are comfortable with the concepts covered in Exercises 5.1, 5.2, and 5.3.

Important Formulas of Arithmetic Progressions
For quick revision, students should remember the following important formulas from Class 10 Maths Chapter 5:
nth Term of an AP
aₙ = a + (n − 1)d
Sum of First n Terms of an AP
Sₙ = n/2 [2a + (n − 1)d]
Sum of First n Terms When Last Term is Known
Sₙ = n/2 (a + l)
where:
a = first term
d = common difference
n = number of terms
l = last term
aₙ = nth term
Sₙ = sum of first n terms
Students should practise using these formulas in different types of questions to become confident with the chapter.
