I've never seen L'Hospital's rule used to calculate a limit of a sequence (sequences don't have derivatives).
Technically you are looking at the limit of but the two limits are equal (as long as you go from the continuous to the discrete anyway). (If you are not convinced suppose otherwise and you will rapidly find a contradiction)

When I was doing series, to be able to use L'Hopital's rule I would simply say:
=
I found that my teacher accepted that, then I could use L'H because I was dealing with a continuous function.
