Question

Select the number from among the given options that can replace the question mark (?) in the following series.
188, 187, 183, 174, 158, ?

A.

133

B.

129

C.

137

D.

139

Correct option is A

Given series:

188, 187, 183, 174, 158, ?

Logic: Square of natural number is decreasing in this number series.

188-12=188-1=187

187-22=187-4=183

183-32=183-9=174

174-42=174-16=158

158-52=158-25=133

So, 133 is the missing number.
Thus, correct option is (a).
