note that

First verify the base case when n=1

So the base case checks

Now we assume it is true for n and show n+1

Now take the derivative of the induction hypothsis to get

lets simplify a bit

and now factor out a 2 to get

but this isn't quite what we want so lets build the fraction by multiplying by (n+1)

and we are done.
