Correct Answer :

Option D

248

Solution :

The correct answer is 248.

To find the value that replaces the question mark (?) in the series, let us analyze the differences between consecutive terms:

28 - 17 = 11
50 - 28 = 22
83 - 50 = 33
127 - 83 = 44
182 - 127 = 55

We can clearly see that the differences are increasing by multiples of 11 (11, 22, 33, 44, 55, ...).

Following this established pattern, the next difference to be added to 182 will be 66:

182 + 66 = 248

Hence, the missing value in the series is 248.
