Step-by-step explanation:
The first term is 9.
Term 1 is 9.
Term 2 is 9 - 3.
Term 3 is 9 - 2(3).
Term 4 is 9 - 3(3).
Term 5 is 9 - 4(5)
Notice the pattern in terms 3 through 5. For each term, subtract 1 less than the term number multiplied by 3 from 9.
For term n, you subtract 1 less than n times 3 from 9.
The nth term is 9 - (n - 1) * 3
Now we simplify the expression on the right side.
The expression for the nth term is
Let's see if it works.
n = 1
n = 2
n = 3
n = 4
n = 5
n = 6
As you can see, following this rule fro the nth term, we got the same first siz terms you got above. Our answer is correct.
