10:00 the series should be from 0 to inf of 3(-1/3)^(n+1), not ^(n-1). But the parts after that were still correct. Great video nonetheless. Keep it up!
@@caseymiltner4991 because, if you plug in 0 for the power as n - 1, you get the first term to have a power of 0-1=-1 and not 1, which was what the original series gave you.
this is so far the clearest explanation I have seen! Thank you so much, this saves my! 😊
at 10:00, if it's (-1/3)^(n-1), then wouldn't you split that into (-1/3)^n * (-1/3)^-1, which in turn would make the second value -3?

why?

5:50 but it isn`t geometric series? or it is?
because n goes 1 to infinite🙄
