(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

showing it is increasing with an upper bound or decreasing

with a lower bound

n/(2^n)

2. Relevant equations

if an >an+1 its underbound

an< an+1 then its upperbound

3. The attempt at a solution

I tried first by finding out the sequence:

a1=1/2

a2=1/2

a3=3/8

a4=1/4

a5=5/32

I'm assuming its decreasing, but I'm not sure if this is monotonic at all. Considering how a1=a2 and then a2>a3 and a3>a4 then a4>a5. I think it's underbound since an>an+1 but the first part threw me off since a1=a2. Someone clarify for me?
