State possible quantum states of electron relaxing from n=4 to n=3 in the order of n,l

Hi all,

I'm right now confused about this.
As far as I know, when changing from a level to another, the change in l (subshell) can only be a difference of 1, and $m_{l}$ can be the same or a difference of 1.
In this case, since the question wants me to state possible quantum states of electron relaxing from n=4 to n=3 in the order of n,l,
is the answer simply just 3,2 / 3,1 / 3,0 ?

Cheers

You're probably expected to enumerate the possible initial states with $n=4$ and indicate the possible final states for each of the initial states.
