Answer: f(7) = f(4) + 3(3) = 15 + 9 = 24

Step by Step Explanation:

f(1) = 6

f(n) = f(n-1) + 3

f(2) = f(1) + 3 = 6+3 = 9

f(3) = f(2) + 3 = 12

f(4) = f(3) + 3 = 15

Each term is 3 more than the previous one

Therefore to get from the 4th term to the 7th term you will add 3

For a total of 3 more times.

f(7) = f(4) + 3(3) = 15 + 9 = 24

Hope this helps
