Calculus II - 9.2.2 The Geometric Series

This is our first "special" series we will learn. Be sure to keep track of what makes a series Geometric, and the conclusion we can draw based on the value of r.

this is so far the clearest explanation I have seen! Thank you so much, this saves my! 😊

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!

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?

5:50 but it isn`t geometric series? or it is?
