Q.

Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?                         
A. (1/3) B. (1/8)
C. (2/8) D. (1/16)

Answer: Option B
Explaination:

 


This is a simple division series; each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.
4/2 = 2
2/2 = 1
1/2 = 1/2
(1/2)/2 = 1/4
(1/4)/2 = 1/8 and so on.
