Hey guys basically, I was reading a text on the atomic emission spectrum and I came across a box that said that the energy levels become closer together as the quantum number increases. Am I right in thinking that the higher the quantum number the lower the difference in energy from the previous energy level?

Any help would be greatly appreciated.

Yes that's true. The energy of the 'n^th' energy level is inversely proportional to n². And hence the difference keeps decreasing as n increases
