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

1.
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.

22-1 = 21 + 2 = 23
23-1 = 22 + 2 = 25.

In this number series, 1 has been subtracted with the first given number, then again 2 has been added with the (subtracted) obtained number.

So, the right answer will be 25.
