Find limit of lim 1^n/(2n-1)?

How do you find the limit of this? I got 0 as the answer but apparently that's not the answer.
sum 1^n/(2n-1)
lim 1^n/(2n-1) = 1/oo = 0

See below.

Explanation:

I am assuming this is a limit to infinity, if not then this is completely wrong.

lim_(n->oo)(1^n/(2n-1))

((2n+1)*1^n)/((2n+1)(2n-1))=((2n+1)*1^n)/(4n^2-1)=(2n+1)/(4n^2-1)

( for limits to infinity we can disregard the constants )

->=(2n)/(4n^2)=1/(2n)

as x->oo , color(white)(88)1/(2n)->0

:.

lim_(n->oo)(1^n/(2n-1))=0

So the limit is 0. Whoever told you it wasn't is wrong.
