I cannot figure out how to write this series in formula summation form. I know it is an alternating series. So far I have:
a_n(n=0 to infiniti) = (-1)^n(3^2n)/(something)
I cannot determine the denominator...
I believe there was also a mistake on the printout of the problem. The third term of the series is supposed to be (2^2)(4^2).
Thank you for any help!
