What is this: S7 ? Do you want the sum of 7 terms?
OpenStudy (anonymous):
It says to find the indicated sum for just S7....

The answer on the book is 4372/3

We'll need the formula to find the first 7 terms of the series. Do you know it?
Directrix (directrix):
972 + 324 + 108 + ... Each term is the previous term divided by 3 so you could just write out the first seven terms and add them.
