Sixth term: 
Step-by-step explanation:
The geometric progression is:

The first term, a, is 9
To find the common ratio, r, all we have to do is divide a term by its preceding term.
Let us divide the second term by the first:

That is the common ratio.
Geometric progression is given generally as:

where a = first term
r = common ratio
= nth term
We need to find the 4th, 5th and 6th terms.
