Question

convergence / divergence ahh. I'm not sure what test to use.. [ (-1)^n * (n+1) ] / (n+2)? I can't decide which test to use. please help :[

Answer 1

sequence or series??

Answer 2

Sorry, i meant to say of a sequence. I'm confused ah. \[[ (-1)^n(n+1) ] \div (n + 2)\]

Answer 3

it's an oscillating sequence ... it neither converges nor diverges

Answer 4

This web puzzle game I am doing posted that question for me and oscillating isn't an option, it gave me convergent or divergent lol. :/
