What does list the allowed energy levels of a bound electron in terms of the quantum numbers n, l, and ml mean?

This is basically asking you to do what Professor Dr. Lavelle did in lecture, where we knew one of the values of the quantum numbers and, using the relationships between those numbers (for example, l = 0, 1, 2, …, n-1 ), found the rest of the quantum numbers.
