The Lyman series is a spectrum series that produces ultraviolet emission lines from any energy level greater than or equal to 2 (n>=2) to energy level of one (n=1). The Balmer series produces emission lines from any energy level greater than or equal to 3 (n>=3) to energy level of two (n = 2).
The answer to 1A.11 is that the principal quantum number for the lowest energy level is the same for all of the lines of a particular series. For example, if you had two emission lines from the Lyman series, one with energy level n=6 and another with energy level n=8 you would know that both of them had the same lowest energy level (n=1) because they are part of that series.

All you need to know is that for the Lyman series the final energy level is n=1, the Balmer series the final energy level is n=2, the Paschen series the final energy level is n=3, and the Brackett series the final energy level is n=4. This can be solved by using quantum equations.
