Question

If given f(1) = -3 and f(n) = -1 . f(n- 1), find the 4th term in the sequence.

A. 1
B. 3
C. -1
D. -3

Answer 1

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).
