<u>Understanding:</u>
The sum of a geometric series is, , with a being the start point and r is the common ratio. We can also use the following formula to make life easier , a is your start point, r is the common ratio, and n is the number of terms, which in our case is S7.
<u>Solution:</u>
Our start point is 1, ,
The common ratio is 5, ,
And finally, the number of terms is 7, .
The answer is [A] 19531.
