Evaluate using the finite geometric sum formula

.

Step-by-step explanation:

The given series is,

When we substitute , we get the first term, which is

This implies that,

.

The common ratio is

The finite geometric sum is given by the formula,

.

Since there are 9 terms, we find the sum of the first nine terms by putting in to the formula to get,
