What will come in place of the question mark (?) in the following number series ?

Question 151

37, ?, 103, 169, 257, 367

Solution

let the missing number be y

y - 37 = ?

103 - y = ?

169 - 103 = 66 = 11 x 6

257 - 169 = 88 = 11 x 8

367 - 257 = 110 = 11 x 10

As we can see that the difference is the even multiple of 11 and the even factor is getting increased by 2 every time.

so y - 37 = 11 x 2

y = 59

103 - 59 = 44 = 11 x 4 (hence our theory got proved.)

So the answer is option D
