The electron in a hydrogen atom is in the first excited state, when the electron acquires an additional 2.86 eV of energy. What is the quantum number n of the state into which the electron moves?(adsbygoogle = window.adsbygoogle || []).push({});

I found the answer to be 5 but I don't know how. I thought I could use the following equation:

En=-(13.6eV) * (z^2 / (nfinal)^2 - (ninitial)^2)

En=-2.86

z=1

ninitial=2

I solved for nfinal and had the answer as 3 but that was incorrect. Am I doing something wrong?

Any help on this would be greatly appreciated! Thank you :)
