Question

Which of the following numbers will replace the question mark (?) in the given series?
30 , 54, 86 , 126 , 174 , ?

A.

230

B.

210

C.

208

D.

220

Correct option is A

Given: 30 , 54, 86 , 126 , 174 , ?
Logic: The double differences between consecutive terms increase by 8
54 - 30 = 24
86 - 54 = 32
126 - 86 = 40
174 - 126 = 48
? - 174 = 56
?  = 174 + 56
? = 230
So the next term in the series is  230
Thus, the correct option is (a)
