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