Question

Find the sum of the following infinite geometric series, if it exists.
1.02 + 2.04 + 4.08 + 8.16 +
does not exist
20
22
24

Answer 1

I don't think it exists?

Answer 2

well each term is doubled... to get the next.

which means that the common ratio for the series is r = 2

an infinite sum can be found when the common is -1 < r < 1

so this series doesn't have an infinite sum

Answer 3

so it doesn't exist

Answer 4

Yep
