Number Series

Directions to Solve

In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much

Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?

(1/3)

(1/8)

(2/8)

(1/16)

Answer: Option

Explanation:

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.
