2. Relevant equations

[tex] \lim_n a_n := \lim_{n \rightarrow \infty} a_n [/tex]

3. The attempt at a solution

I'm stuck at exercise (c). Since if n heads to infinity the m doesn't play the role the limitmust beone. So the mistake is somewhere on the left and I think it is at the part where both limits are taken at the same time.

Or is the limit 1/2? Can someone help me?
