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
