(-1)^n(x+2)^n

______________

sqrt(n)*3^n

i use the ratio test abs(bn+1/bn), then plug and chug and I get:

sqrt(n)|x+2|

___________

3*sqrt(n+1)

=

|x+2|

________

3

the problem is, i try maple and it gets absolutely no where near that...rather, it gets infinity.???

I need to be able to find the int of convergence. thanks
