from n=0 (sigma sign) to infinity of ((n+4)/(n!))

I know I need to use the ratio test. What I'm setting it up as is.

lim as x --> infinity of ((n+5)/(n+1)!) / ((n+4)/(n!))

Is this the correct setup when evaluating the limit?

Thank you.

I feel like it doesn't because it decreases too slowly. I need it to find the value of the integral from 2 to infinity of 1/(x(lnx)squared). The integral ends up being -1/(lnb) + 1/(ln2). as b approaches infinity
