Show answer & explanation

Correct answer: D

The series is:
11, 23, 47, 83, 131

Find the differences:
23 - 11 = 12
47 - 23 = 24
83 - 47 = 36
131 - 83 = 48

The differences are 12, 24, 36, 48; each increases by 12. Therefore, the next difference is 60.

Next term = 131 + 60 = 191.

Therefore, option D is correct.
