Doing so already :)

Wait shoot, shouldn’t the second series be convergent too?pic.twitter.com/Tj1mRzQ3dd
-
Convergence: |x - a| < R. Divergence: |x - a| > R idek???: |x - a| = R Now, for part b, 2 = 7-5
-
But if R needs to be greater than 2 for x = 3 to be convergent, wouldn’t x = 7 be convergent too?
-
hm, true. let me a little think
-
Ah, right. Both points are on what we can best guess to be the boundary. So idek?? holds there, but we're given x=3 is good.
-
I can write that up more formally if you want :)
-
If you have time that’d be rad! Thanks so much
-
sure thing, gimme a couple minutes!
