<u>Answer:</u>
The correct answer option is H. 4374.
<u>Step-by-step explanation:</u>
We are given the following geometric sequence and we are to find its 8th term:

Here
and common ratio
.
The formula we will use to find the 10th term is:
nth term = 
Substituting the values in the formula to get:
10th term = 
10th term = 4374
22 quarters= $5.50
10 dimes= $1.00
$5.50 + $1.00 = $6.50
I just did trial and error. I started with 20 quarters and made changes until it worked.
