#### Answer

Yes, it would have an effect.

#### Work Step by Step

If the energy spacing between 1 and 2 were equal to the spacing between 2 and 3, there would be only two unique spectral lines. A transition between the n=3 level and the n=2 level would emit the same-energy photon as a transition between the n=2 level and the n=1 level. The other spectral line would be due to a transition between the n=3 level and the n=1 level.
