16, 37, 79, 142, 226, ?

A.

307

B.

309

C.

D.

331

Correct option is D

Given: 16, 37, 79, 142, 226, ?
Logic: Difference is multiple of 21.
16 + (21 ×\times 1) = 16 + 21 = 37
37 + (21 ×\times 2) = 37 + 42 = 79
79 + (21 ×\times 3) = 79 + 63 = 142
142 + (21 ×\times​ 4) = 142 + 84 = 226
226 + (21 ×\times 5) = 226 + 105 = 331
Alternate Solution:
So, the missing term is 331.
Thus, correct option is (d).
