Answer 1

Heyyy its youu! Still bored and giving away points I see? :) Well here's my answer : sooo each number is the previous number divided by 2 and that means the common ratio is 1/2. The way I figured that out is to find the common ratio you need to divide the prev. number by that #.

Answer 2

divided by 2 = 1/2

r = 1/2
