Example 3: Test for Convergence

Test the series 09_infinite_series-181.gif for convergence. Intuitively, the 7n

should overcome the -5n, so we shall compare with 6n/7n. The simplest approach is to factor out 7n. We have


The geometric series 09_infinite_series-183.gif is convergent, so the given series converges.
