do you mean non-decreasing?

if it can't increase, how can it go to infinity?

i'm not sure because that is what the problem has.

it's actually not bounded below and goes to negative infinity

y=2 is a non-increacing sequence that doesn't diverge

ok. so how would write a proof for that.

what is it exactly that you have to prove?

i want to prove that a non-increasing sequence that isn't bounded below diverges

OpenStudy (anonymous):

i don't think that's the case unless there's more info

its just any sequence. there's no other information to the statement.
