Well, this thread is purposely to clarify my question on the use of L'Hospital's rule for sequence.

As I have read from the calculus book, the sequence can be defined such thatf:N → ℝwith functionf(n)= awhere_{n}ninside natural numbers,N.

So, we cannot apply L' Hospital rule directly is because the function above isdiscontinuouson natural numbers and thennot differentiable?

2. Relevant equations

When we plot the graphf(n)versusn, we don't have a continuous graph. Is this mean discontinuous?

3. The attempt at a solution
