Answer:
Sequence converges.
Limit = 96
Explanation:
We are given series 72, 18,
,
, ..........
First we find the common ratio of the given series.
Ratio (r) =
=
=
=

Here, ratio of the series equal. So, it would be converges.
Now we find the limit of the sequence.
Formula =

where, a=72 and r=

Limit=

Limit =

Limit=96
