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

Question: 190, 166, 145, 128, 112, 100, 91
[A].

100

[B].

166

[C].

145

[D].

128

Answer: Option D

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.
