Final answer:
To find the value of f(1) in the given sequence defined by the formula f(n+1) = f(n) - 3, we can work backward from f(4) = 22. The value of f(1) is 13.
Step-by-step explanation:
To find the value of f(1) in the given sequence defined by the formula f(n+1) = f(n) - 3, we can work backward from f(4) = 22. To construct a proof from the given premises, the student is required to use principles of logical inference. When evaluating arguments, one must assess both the logical structure and the truth of the premises. In philosophy
We start with f(4) = 22, and then use the formula to find f(3) = f(4) - 3 = 22 - 3 = 19.
Continuing this pattern, we find f(2) = f(3) - 3 = 19 - 3 = 16, and finally f(1) = f(2) - 3 = 16 - 3 = 13.
Therefore, the value of f(1) is 13, which corresponds to option D.
