n this progression, for a given series, the terms used are the first term, the common difference between the two terms and nth term.

Suppose, a_{1}, a_{2}, a_{3}, ……………., a_{n} is an AP, then;_{ }the **common difference “ d ”** can be obtained as; In this progression, for a given series, the terms used are the first term, the common difference between the two terms and nth term.

**Exercise- 5.2 Question No. 4 :**

**Which term of the A.P. 3, 8, 13, 18, … is 78?**

**Class 10 Exercise 5.2 Question No. 4 Solutions**

3, 8, 13, 18, …

For this A.P.,

*a* = 3

*d* = *a*_{2} − *a*_{1} = 8 − 3 = 5

Let *n*^{th} term of this A.P. be 78.

**a _{n} = a + (n − 1) d**

78 = 3 + (

*n*− 1) 5

75 = (

*n*− 1) 5

(

*n*− 1) = 15

*n*= 16

Hence,

**16**

^{th}term of this A.P. is 78.## **OR**
