Find the sum of the first 9 terms in the following geometric series.
Do not round your answer.
64+32+16+...64+32+16+...64, plus, 32, plus, 16, plus, point, point, point

The sum of the first 9 terms is .

Step-by-step explanation:

To find the sum of the first terms of a geometric sequence use the formula

where, is the number of terms, is the first term and is the common ratio.

To find the common ratio, find the ratio between a term and the term preceding it.  

Given the geometric sequence , the common ratio is

and the sum of the first 9 terms is

26?
