Question

2, 1, (1/2), (1/4), __

• A. 1/8
• B. 1/12
• C. 1/16
• D. 1/20
• E. 1/22

Answer 1

The correct option is A

1/8

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.

$\frac{4}{2}=2$

$\frac{2}{2}=1$

$\frac{1}{2}=\frac{1}{2}$

$\frac{1}{2}.\frac{1}{2}=\frac{1}{4}$

$\frac{1}{4}.\frac{1}{2}=\frac{1}{8}$ and so on.
