The questions says "In the ultraviolet spectrum of atomic hydrogen, a line is observed at 102.6 nm. Determine the values of n for the initial and final energy levels of the electron during the emission of energy that leads to this spectral line."

How do we begin to solve this question? Should the equation V=R{(1/n1^2)-(1/n2^2)} be used or is there a simpler way of answering the question?

The equation you listed is the correct one to use. The tricky part is recognizing that at 102.6nm, the line observed is a part of the Lyman series

This would mean that

Now that we know what one value of n is, we can find by using the formula
