Question

Select the wrong term in the following number series:
9, 10, 19, 44, 93, 175

A.

10

B.

175

C.

93

D.

44

Correct option is B

Given: 9, 10, 19, 44, 93, 175
Logic: Difference is a perfect square of odd number from 1.
10 - 9 = 1\sqrt {1}​​ = 1
19 - 10 = 9\sqrt {9}​ = 3
44 - 19 = 25\sqrt {25} = 5
93 - 44 = 49\sqrt {49} = 7
175 - 93 = 82\sqrt {82} \neq 81\sqrt {81}​ = 9
So, the wrong term is 175.
Thus, correct option is (b).
