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) = –3 f(n ) f (n + 1) = 3 f(n ) f (n + 1) = –2 f(n ) f (n + 1) = 2 f(n)

, where f(1)=3

Step-by-step explanation:

The given sequence is; 3, –6, 12, –24, 48, …

The first term of this sequence is

There is a common ratio of

We can actually use any other two consecutive terms in the sequence to obtain the common ratio.

The recursive formula is given by:

We plug in the common ratio to get:

, where f(1)=3
