Limit with criteria limntoinftyncdotleft[frac1eleft(1+frac1n+1right)n+11right]

limnn[(1+1n+1)n+1e1]



I was trying to calculate a limit that drove me to this case of Raabe-Duhamel's test, but I don't know how to finish it. Please give me a hint or a piece of advise.



I cannot use any of the solution below, but they are clear and good. I'm trying to prove it using squeeze theorem like this:
limnn[(1+1n+1)n+1e1]=1elimnn[e(1+1n+1)n+1]


I found this:
$$\frac{e}{2n+2}
Is this true? How can I prove this? Thanks for the answers.
