Select the correct choice below and fill in the answer box to complete your choice.
A. The series is a geometric series with common ratio
This is less than 1, so the series diverges by the
properties of a geometric series.
(Type an exact answer.)
B. The series is a geometric series with common ratio
This is greater than 1, so the series diverges by
the properties of a geometric series.
(Type an exact answer.)
C. The Ratio Test yields r =
This is less than 1, so the series converges by the Ratio Test.
