Evaluate the convergence of the series n=3∑∞(n−2)7n7n−3.
a) It converges by the Ratio Test since the common ratio is 71<1.
b) It diverges because its terms do not approach zero.
c) It diverges because the series reduces to a constant multiple of the harmonic series.
d) It converges by comparison to a p-series with p=2.
