Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1?

3, –6, 12, –24, 48

The recursive formula for this sequence is

f (n + 1) = –2 f(n)

at n=1 f(n)= 3

at n = 2

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

n = 3

f(3) = -2 (-6) = 12 and so on

The recursive formula for the sequence is:
f(n+1) = -2f(n)

Let's take an example:
Let f(n) = 12 and we need to calculate f(n+1) which should be -24
If we apply the formula than the answer is:
f(n+1) = -2*12 = -24.

I hope that this is the answer that you were looking for and it has helped you.

jeyben [28]

Answer:

9 and 12

Step-by-step explanation:

Pythagorean Theorem. One of the most common Pythagorean triples is 3, 4, 5 with 3 and 4 the legs and 5 the hypoenuse. That will make 9, 12, 15 anotther trible because you are tripling the side lengths. 12-9=3 so this triangle works.
