>sandwich theorem
No. At least, I don't think so. There could also be a version of this called the sandwich theorem.
Technically, the first inequality [math]should [/math] give you that the radius is smaller than [math]1[/math] (because it's term-wise larger than a divergent series, the geometric one) and the second one that the radius is at least [math]1[/math] (because it's term-wise smaller than a convergent series, again the geometric). The inequalities have just been juxtaposed for convenience.
