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:
If you would like to calculate 57 divided by 8, you can do this using the following steps:
57 divided by 8:
57 / 8 = 7 1/8 = 7.125
The correct result would be 7 1/8 or 7.125.
