On page 2 of the spring 2020 tests solutions, there is the following question and solution and associated solution. How do we find the limit of n(n^2+1)^2/3(n+1)((n+1)^2 + 1)^2

Thx, but I meant in the very first post with a screenshot of the official solution it has 1/2n(2n+1),so I was just confused as to which one was the correct answer.

Shouldn't it be 2n(n+1) in the denominator, not 2(n+1)?

Don't we need to have 1/2n(2n+1) not 1/(2n+2)(2n+1) ?
