*NCERT Solutions for Class 10 Maths (Introduction)*

### Arithmetic Progressions of exercise 5.3 *(Class 10 Maths exercise 5.3)* you have studied the following points:

- An arithmetic progression (AP) is a list of numbers in which each term is obtained by

adding a fixed number d to the preceding term, except the first term. The fixed number d

is called the common difference.

The general form of an AP is a, a + d, a + 2d, a + 3d, . . . - In an AP with first term a and common difference d, the nth term (or the general term) is

given by an= a + (n – 1) d. - The sum of the first n terms of an AP is given by : S=n/2[2a+(n-1)d].
- If l is the last term of the finite AP, say the nth term, then the sum of all terms of the AP

is given by : S=n/2(a + l). - If a, b, c are in AP, then b=(a + b)/2 and b is called the arithmetic mean of a and c.

**NCERT Solutions** for Class 10 Maths Chapter 13 Surface areas and volumes for all boards. We have updated all the contents for the new academic session 2020-2021.

From Class IX, you are familiar with some of the solids like cuboid, cone, cylinder, and sphere. You have also learned how to find their surface areas and volumes. In our day-to-day life, we come across a number of solids made up of combinations of two or more of the basic solids. In this exercise, you will see how to find surface areas and volumes of such objects.
