No, the term n is the variable for energy level. Suppose an electron moves from n= 3 to n= 2 and you want to find the change in E. You would then plug the initial n into the Rydberg equation and do the same for the final n. Then you solve E(final)-E(initial) to find (delta)E. The term n^2 is not the initial energy level, it is part of the Rydberg equation in which you plug in the energy level to solve for the E at that level.

As Will said in their post, the "n^2" in the denominator does NOT refer to the initial energy level. "n", unless otherwise specified, is just an energy level.
In the case of the example problem from today's lecture, we were given an initial and final energy level and we needed to find the difference in energy between the two levels. Because of this, we used the given equation twice - once for the initial energy level and again for the final energy level.
To find the actual change in energy you would do final - initial with the values you found.
