Which recursive formula can be used to generate the sequence shown, where f(1) = 9.6 and n > 1?
9.6, –4.8, 2.4, –1.2, 0.6, ...
f(n + 1) = –0.5f(n)
f(n + 1) = 0.5f(n)
f(n + 1) = f(0.5n)
f(n + 1) = f(–0.5n)

Best ResponseYou've already chosen the best response.0think of \(f(n)\) as 'some term', and \(f(n+1)\) as 'the term afterward'  this should make it potentially easier to understand

Best ResponseYou've already chosen the best response.0hmmm test the sequence pattern, see if it gives you those numbers

Best ResponseYou've already chosen the best response.0keep in mind that f(n+1) simply means "the following number" so if you're in the 3rd term, n = 3, and want the 4th term, or n+1 then that'd be n = 3, thus n+1 is 3+1 or f(4) and so on

Best ResponseYou've already chosen the best response.0well, you could try testing the given choices see which one gives you the correct next value
