The Bohr Model of Atomic Structure Practice Test

A hydrogen electron can occupy only Bohr orbits $n=1,2,3,4$; all intermediate energies are forbidden. If the electron emits the highest-energy photon, which jump occurred?

In a Bohr-model ion, allowed energies correspond to $n=1,2,3,4$ and energies between are forbidden. An electron is excited from $n=2$ to $n=4$. What must occur?
