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.

4/2 = 2 how come?
The series itself starts with 2, then it could be like this.
2/2 =1 ,
1/2 = 1/2 ,
1/2÷2 = 1/4 ,
1/4÷2 = 1/8.

4/2=2,
2/2=1,
(1/2)/2=1/4,
(1/4)/2=1/8.
Then all terms are divided by 2 one by one.
2/2=1,
(1/2)/2=1/4,
(1/4)/2=1/8.
Then all terms are divided by 2 one by one.

1/2 = 1/2.
(1/2)2 = 1/4.
(1/4)/2 = 1/8.
2/2 = 1.
1/2 = 1/2.
(1/2)2 = 1/4.
(1/4)/2 = 1/8.
