What it looks to be that you found in A was the "initial" ... b/c the question asks:

"how much energy does the electron have 'initially' in the n=4 excited state?"

"final" would be where it 'finally' ends up at, ie. its last stop ... as for this question ... the 'ground state' as in its lowest energy level.

The answer comes to: - 1.36*10^-19 J

You use the same equation for the second part as for part a.

just have to subract the 2 as in the only diff for part 2 is that you use 1squared rather than 4squared & subract "final - initial" & you should get - 2.05*10^-18 as your answer.
