ok im a little lost on this problem...

if n is less than and equal to -2, which of the following has the least value?

a. -$\displaystyle \frac{1}{n^{2}}$

b. $\displaystyle \frac{1}{n^{2}}$

c.$\displaystyle \frac{1}{n}$

d.$\displaystyle \frac{1}{n-1}$

e.$\displaystyle \frac{1}{n+1}$

to do this problem i plugged in values, so i chose n= -5 and selected a as my answer...but of course this is wrong, i would like to know why.

thanks in advance.
