Find the sum of the geometric sequence –3, 15, –75, 375, … when there are 9 terms and select the correct answer below.

1 answer:

3 0

The correct answer to the question presented above would be letter A. -976, 563. I got this through solving with the first number of the set, then getting the ratio of the data set (which is -5) and the number of terms in the set. Thus, I arrived with the answer, -976, 563.
