What should come in place of the question mark (?) in the given series?
102, 108, 120, 138, 162, ?

Correct option is D

Given: 102, 108, 120, 138, 162, ?
Logic: The differences are increasing by 6 each time 6, 12, 18, 24, 30..
102 + 6 = 108
108 + 12 = 120
120 + 18 = 138
138 + 24 = 162
162 + 30 = 192
So, ? = 192
Thus, the correct option is (D) 192
