The Alternating Series Test: conditions for convergence
decreasing
lim --> infinity ak = 0
The Attempt at a Solution
I am not sure how to find out if the series is decreasing. Since it is a factorial, I cannot take the first deriative test.
I was wondering if I should use the Alternating Series Test at all, since it is an factorial.
Can someone help me here?
