Graph the six terms of a finite series where a1 = −3 and r = 1.5.

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:
