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)

Best ResponseYou've already chosen the best response.2or since they gave you choices, you can just try each one out to see which works w/o knowing anything

Best ResponseYou've already chosen the best response.2the first term f(n) is 3 given to you, put that in each answer choice and see which gives back the next value in the sequence
