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.

According to the question.
Look at this series: 2, 1, (1/2) , (1/4) , . What number should come next?
Principle we need to follow this. This is a simple division series; each number is one-half of the previous number. 1 * 1/2 = 1/2.
2 * 1/2 = 2/2 =1.
1/4 * 1/2=1/8 so the answer is 1/8.
Let me know is there any mistake feel free to tell me because me also pure in maths.

By dividing every number with 2 we can get the answer as 1/8.

Another logic of this sum is; Divide the given number by 2, then you will get the answer. Check it.
