Correct option is B
Given: 33, 80, 108, ?, 183, 230, 258
Logic: Alternating pattern of +47 and +28
Find the difference between consecutive terms:
· 80 - 33 = 47
· 108 - 80 = 28
· ? - 108 = x
· 183 - ? = y
· 230 - 183 = 47
· 258 - 230 = 28
Notice the alternating pattern of +47 and +28.
So, the missing number should follow this pattern:
? - 108 = 47
Therefore, ? = 108 + 47 = 155.
Thus, the missing number in the series is 155.
