When determining whether a series is convergent or not, state the test you use to

make the determination and show that the conditions of the test are met.

1. Provide an example of an alternating series that does not converge even though

it meets all the conditions of the Alternating Series Test except the one that

anan+1 for all natural numbers n. When you come up with this example,

you'll have demonstrated why this condition is needed.

2. Determine whether the series
