Question

what will be 17^th term in the following Arithmetic progressive series 3, 7, 11, 15, __
1. 63
2. 71
3. 67
4. 59

Answer 1

Correct Answer - Option 3 : 67

3, 7, 11, 15, __

This is an AP.

Difference d = 4

a = 3

n = number of terms = 17

Formula Used:

nth term = a + (n - 1) × d

17th term = 3 + (17 - 1) × (4)

= 3 + 16 × 4

= 3 + 64

= 67

Hence, 17th term is 67.
