## Homework Statement

Determine which of the sequences converge or diverge. Find the limit of the convergent sequences.

1) {asubn}= [((n^2) + (-1)^n)] / [(4n^2)]

## Homework Equations

[/B]

a1=first term, a2=second term...an= nth term

## The Attempt at a Solution

a) So I found the first couple of terms

a1=0

a2=5/16

a3=2/9

a4=17/64

It didn't really look like it converged, but I took the limit as n approached infinity, divided the highest degree in the numerator and the denominator and got the limit to be 1/4. [/B]
