Logical Reasoning - Number Series - Discussion
Discussion Forum : Number Series - Type 1 (Q.No. 1)
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?
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.

Suppose that it is 2, 1, (1/2), (1/4).
Than we can easily understand by doing this in this way.
Second number multiplied from first number and then get the next number.
Like: 1/2 * 1/4 = 1/8 solved.

2, 1, 1/2, 1/4, ?......2, 1, 0.5, 0.25.
See that series clearly know divided by 2, get next number.
So, 0.25/2 = 1/8.

The series is geometric progression.
a2 divide by a1 so 1/2 and a3 by a2 so 1/2/1/1.
So the comment ratio is 1/2.
2, 1, 1/2, 1/4, 1/8.
a2 divide by a1 so 1/2 and a3 by a2 so 1/2/1/1.
So the comment ratio is 1/2.
2, 1, 1/2, 1/4, 1/8.

4*1/2 = 2.
2*1/2 = 1.
1*1/2 = 1/2.
1/2*1/2 = 1/4.
1/4*1/2 = 1/8.
2*1/2 = 1.
1*1/2 = 1/2.
1/2*1/2 = 1/4.
1/4*1/2 = 1/8.
