Q:

Find the odd man out of the series 888, 440, 216, 104, 48, 22, 6 ?

A) 104	B) 48
C) 22	D) 216

Answer & Explanation Answer: C) 22

Explanation:

In the given series,

2nd term = $\frac{1 s t t e r m - 8}{2} = \frac{888 - 8}{2} = 440$

3rd term = $\frac{2 n d t e r m - 8}{2} = \frac{440 - 8}{2} = 216$

and so on...

Here 6th term = $\frac{5 t h t e r m - 8}{2} = \frac{48 - 8}{2} = 20$

Therefore, 22 is wrong.
