I am confused about the right formula for this. Is it
[itex] R_{n} \leq T_{n} \leq \int_{n+1}^{\infty} [/itex] or [itex]R_{n} \leq T_{n} \leq\int_{n}^{\infty} [/itex]?
Say for example, I want to estimate the error in using the sum of the first 10 terms to approximate the sum of the series.
The textbook seems to use both methods (Use n for the p-series and n+1 for the geometric series)
(as seen in the examples here)

and I am quite confused which it is the right way. I am wondering if someone could clear this up for me. Thanks!
