Using the recursive function given, it is found that f(5) = 6600.
The function given is:
[tex]f(n + 1) = f(n) - 400[/tex]
[tex]f(1) = 8200[/tex]
To find f(5), we keep applying the function until [tex]n + 1 = 5[/tex], hence:
f(2) is f(1) subtracted by 400
[tex]f(2) = f(1) - 400 = 8200 - 400 = 7800[/tex]
f(3) is f(2) subtracted by 400
[tex]f(3) = f(2) - 400 = 7800 - 400 = 7400[/tex]
f(4) is f(3) subtracted by 400
[tex]f(4) = f(3) - 400 = 7400 - 400 = 7000[/tex]
f(5) is f(4) subtracted by 400
[tex]f(5) = f(4) - 400 = 7000 - 400 = 6600[/tex]
Hence, the result is f(5) = 6600.
