Answer:

f(5) = -10

Explanation:

Let's go through the calculation step by step to find the value of f(5) using the given recursive formula f(n) = f(n-1) - 3.

Start with the initial value f(1) = 2, as given in the problem.

To find f(2), we use the recursive formula f(n) = f(n-1) - 3. Since n = 2, we have f(2) = f(1) - 3. Plugging in the value of f(1) as 2, we get f(2) = 2 - 3 = -1.

Continuing the pattern, we find f(3) = f(2) - 3 = -1 - 3 = -4. We subtract 3 from the previous term f(2) to obtain f(3).

Moving on, f(4) = f(3) - 3 = -4 - 3 = -7. Again, we subtract 3 from the previous term f(3) to calculate f(4).

Finally, f(5) = f(4) - 3 = -7 - 3 = -10. Following the recursive formula, we subtract 3 from the previous term f(4) to determine f(5).

Therefore, the value of f(5) is -10.

Hope this helps!
