Ответ:
In the given geometric series, r, the common ratio is 7/9; therefore the series is convergent.
Step-by-step explanation:
We are given the geometric series:
The general geometric series is in the for
, where a is the first term and r is the common ratio.
Comparing with the given geometric series, we have,![a = \frac{1}{9} \text{ and }r = \frac{7}{9}](/tpl/images/0131/6757/696a4.png)
If r > 1, the series is divergent.
If r < 1, the series is convergent.
In the given geometric series, r, the common ratio is 7/9; therefore the series is convergent.
