1. Look at this series: 2, 1, (1/2), (1/4), ... What number should come next?
A. ([latex]\frac {1}{3}[/latex]) B. ([latex]\frac {1}{8}[/latex]) C. ([latex]\frac {2}{8}[/latex]) D. ([latex]\frac {1}{16}[/latex])
Answer: Option B
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.
[latex]\frac {4}{2}[/latex] = 2
[latex]\frac {2}{2}[/latex] = 1
[latex]\frac {1}{2}[/latex] = [latex]\frac {1}{2}[/latex]
[latex]\frac{\frac {1}{2}}{2}[/latex] = [latex]\frac {1}{4}[/latex]
[latex]\frac{\frac {1}{4}}{2}[/latex] = [latex]\frac {1}{8}[/latex] and so on.
