What should come in place of the question mark (?) in the given series?
108, 122, 139, 159, 182, 208, ?

108, 122, 139, 159, 182, 208, ?

Logic: Differences are increasing by +3 each time:​

122 − 108 = 14

139 − 122 = 17

159 − 139 = 20

182 − 159 = 23

208 − 182 = 26

next = 29

So,
208 + 29 = 237

Thus, correct option is (B) 237.
