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.
