Match each series to the test that should be used to test for convergence/divergence. While it is possible that each test could apply to more than one series, in this exercise each is only used once. [infinity]

a. ∑2^n/n!

n=1

[infinity]

b. ∑n^2

n=1

[infinity]

c. ∑(-1)^n+1 (n+1)/(3n+1)

n=1

1. Alternating series.

2. Geometric series.

3. Ratio test.

4. nth term test.

this is a very good question

step-by-step explanation:

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
