 The required common ratio is 0.79.

Step-by-step explanation:  Given that in a geometric series, each term is 21% less than the previous term.

We are to find the common ratio r for this geometric series.

Let the first term of the give geometric series be a.

Then, according to the given information, the second term of the geometric series will be

In a geometric series each term is 21% less than, №15216788, 08.11.2022 23:53

Therefore, the required common ratio for the given geometric series is given by

In a geometric series each term is 21% less than, №15216788, 08.11.2022 23:53
