we know that
A <u>geometric sequence</u> is a sequence of numbers in which the ratio between consecutive terms is constant
so
Let
therefore
The common ratio is equal to 
<u>the answer is</u>
The common ratio is 1.02
-8 ≤ 8 + y
- Subtract 8 from both sides.
-16 ≤ y
- Flip this around so y is first.
<h3>y ≥ -16</h3>
