Prove:

The sequence converges to

I don't even know what method to use to show:

1. that this converges, and

2. that it converges to that value.

Any help with this one?

What's a good method to show that the limit exists for this sequence? I've tried showing that it's contractive, but no luck there. Tried the ratio test, didn't work for me. Any ideas?
