Final answer:
The 4th term in the sequence is 3.
Step-by-step explanation:
To find the 4th term in the sequence, we can use the given formula f(n) = -1 * f(n-1). We are given f(1) = -3. Starting from f(1), we can calculate each term by using the formula.
f(2) = -1 * f(1) = -1 * (-3) = 3
f(3) = -1 * f(2) = -1 * 3 = -3
f(4) = -1 * f(3) = -1 * (-3) = 3
Therefore, the 4th term in the sequence is 3 (Option B).
