Hi, I'm not sure how to figure out this problem:

Let

A. Find the smallest real number such that is decreasing for all greater than

B. Find the smallest integer such that is decreasing for all integers greater than or equal to .

Also, I need help with finding the equation $\displaystyle A_{n}$ for this sequence: $\displaystyle \frac{3}{16},\frac{4}{25},\frac{5}{36},\frac{6}{49 }$ I Know that there is going to be n+2 on the numerator but I can't figure out the denominator, so its $\displaystyle \frac{n+2}{x}$ and I need help finding x.

Regards,

Matt
