option A is correct
Step-by-step explanation:
Hope it helps
We are given the first term and the common ratio, this means they belong to a geometric series.
For the given series:

Each term of the geometric series is obtained by multiplying the previous term by common ratio.
So the next terms will be:
-4.5, -6.75, -10.125, -15.1875, -22.78125
The general formula for the G.P would be:

On plotting the series, the result will be like this:
First find slope we use : m=y2-y1/x2-x1
1) 20-8/12-2 = 8/10 in simple form 4/5
