190, 166, 145, 128, 112, 100, 91

Correct Answer: 128

Explanation:

Go on subtracting 24, 21, 18, 15, 12, 9 from the numbers to get the next number.


190 - 24 = 166
166 - 21 = 145
145 - 18 = 127 [Here, 128 is placed instead of 127]
127 - 15 = 112
112 - 12 = 100 ... and so on.

Therefore, 128 is wrong.
