1. The problem statement, all variables and given/known data

show that if Xn is bounded and Xn>=Yn for all n, then lim sup Xn >= lim sup Yn

2. Relevant equations



3. The attempt at a solution

I know that if I can show that y<= some fixed number, then I can show that lim sup y<=that number, but I'm not sure how to show that Yn<a fixed number...

Have you tried a proof by contradiction?
