So the two energy states are n=4 and n=inf

Use the Rydberg equation, right?

yes this is the right equation- but idk why you use this and why u know from the problem to use 1/infinity...

1. If you REMOVE an electron from hydrogen, you move it to infinity (or at least so far away it may as well be at infinity). But putting infinity into the Rydberg equation gives you 1/infinity for that part of the equation and 1/infinity = 0.
