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]
