Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1? 3, –6, 12, –24, 48, … f (n + 1) =

What recursive formula applies to generate the following sequence where f(1) = 3 and n ≥ 1?

3, –6, 12, –24, 48

The applicable recursive formula for this sequence is

f(n + 1) = –2 f(n)

When n=1, f(n) equals 3

Now when n = 2

f(2) = -2 (3) = -6

When n = 3

f(3) = -2 (-6) = 12, and this pattern continues.

The formula to recursively establish the sequence is:
f(n+1) = -2f(n)

Let's consider an example:
If we set f(n) = 12 to find f(n+1), it should yield -24
Using the formula, the result would be:
f(n+1) = -2*12 = -24.
