Answer:
The nth term is given by: 
The 30th term is 78.
Step-by-step explanation:
Arithmetic sequence:
The nth term of an arithmetic sequence is given by:

In which
is the first term and d is the common difference between terms.
-9, -6, - 3,0
This means that
. So

30th term:

The 30th term is 78.
Both 15 and 20 can be divided evenly by 5, so 5 is the greatest common monomial: 5(3x^2 + 4x) or 5x(3x + 4)
