WebIf we take the ratio to be 2, then the result of the sum would be +infinite. But let's put it in numbers in the same way Sal did: X = 5 + 5*2 + 5*2² + 5* 2³ etc.... now we multiply X by r, which is 2, and then let's subtract them. Now, X-2X = 5 X=5/1-2 X=-5 (!) What's wrong with this logic? It should be +infinite, right? • ( 24 votes) Ethan Dlugie WebThe difference between the example and the practice problem is in the question itself.
