Determine if the following sequence:
{ (n + 1)^2 / (n^2 + 1),
is ascending, descending and find the lower bound b OR the upper bound B.
So I found that the sequence is descending changing the n's for x's and using the derivative. But now I'm not sure on how to proceed to find either of the bounds.

so I realized it's not using the derivative that we find if a sequenec is ascending/descending, but rather comparing the series. Nonetheless, the sequence is still descending.
