For the following series, write formulas for the sequences an,
Sn and Rn, and find the limits of the sequences as n-->infinity
The Attempt at a Solution
an is easy, =
the limit of which does not exist.
This is where I get stuck, I know Sn=
But I don't know how to come up with an actual formula for the sum. Furthermore, I'm not sure I even know what Rn is, a Reimann sum? How do I go about doing that? I can't find anything in my notes.
