29. Sum to n terms the series whose nth term is​

Answer 1

Step-by-step explanation:

am trying to calculate the sum of this infinite series after having read the series chapter of my textbook:

∑n=1∞14n2−1

my steps:

∑n=1∞14n2−1=∑n=1∞24n2−1−∑n=1∞14n2−1=..help..=sum

I am lacking some important properties, I feel I am coming to the right step and cannot spit that out..
