12,17,32,57,92,? ​​

A.

112

B.

122

C.

157

D.

137

Correct option is D

Given:
12, 17, 32, 57, 92, ?
Logic:
Difference of two constitutive number is in incresing from 5, 15, 25, 35
17−12=5
32 − 17 = 15
57 − 32 = 25
92 − 57 = 35 
The differences are increased by 10 of two constitutive number
​The next difference is 35 +10 = 45
Add the next difference to the last term
92+45= 137
Thus, correct option is (d)
