Now in this problem I've attached, I was almost positive the answer would be 0 since the denominator will be approaching an infinitely large number, but I guess this isn't the case. Could someone tell me why the answer isn't 0 and how to go about doing this problem?
Hello, fattydq!
Be careful about what you're referring to . . .
Now in this problem I've attached, I was almost positive the answer would be 0 . no
since the denominator will be approaching an infinitely large number.
The terms are approach 0 . . . this is true.
. . But the answer (what they are asking for) is the sum of the series.
We have: .
This is a geometric series with first term and common ratio
Its sum is: .
