Can the sum of a geometric series be negative
http://mathcentral.uregina.ca/QQ/database/QQ.09.00/carter1.html WebHere we see: ∑ 2* (-4x^2)^n, where the common ratio is (-4x^2). I would THINK that if you can break up your common ratio into the sum of an x-varying part minus a constant part, so it looks like (x-c), then that would show that the series is centered at the constant part. Example: ∑ 2* [ ( 4b^2) - 5]^n. The common ratio is (4b^2)-5.
