Consider the series: 1-1/2 -1/3 +1/4 +1/5 -1/6 -1/7........where the signs come in pairs. Does the series converge or diverge? I want to use the alternating series test....any ideas? how I would solve this. Thanks

but in your case we get a plus and then a minus.....but the series is minus minus ...plus plus?

Note this is the series listed above I just gave the general term. Since we can look at the new series to draw any needed conclusions.
