**CBSE NCERT Solutions Chapter 5 Arithmetic Progressions Exercise 5.2 Question 2**

**2. Choose the correct choice in the following and justify:**

**(i) 30th term of the AP: , is**

**(A) 97 (B) 77 (C) -77 (D) -87**

**(ii) 11th term of the AP: , is**

**(A) 28 (B) 22 (C) -38 (D) **

**Solution (i) **

First term = a =10

Common difference = d = 7- 10 = 4-7 = -3

n = 30 {Because, we need to find 30th term}

Therefore, the answer is **(C)**

**Solution (ii) **

First term = a = -3

Common difference = d =

n = 11 (Because, we need to find 11th term)

Using formula , to find 11th term, we get

Therefore 11th term is 22 which means answer is **(B)**.
