The following function defines a recursive sequence.
f(0) = 5
f(1) = 20
f(n) = 4•f(n 1)  3•f(n  2); for n > 1
Which of the following sequences is defined by this recursive function?
5, 20, 65, 200, …
5, 20, 92, 372, …
5, 24, 92, 372, …
5, 20, 65, 200, …

Best ResponseYou've already chosen the best response.3yes, so they give you the first one what is the second term?

Best ResponseYou've already chosen the best response.3we can narrow the options by eliminating the ones that have the wrong first and second terms, then the third term gets us to only one option that fits

Best ResponseYou've already chosen the best response.3we can use the rule given to determine f(2) f(n) = 4•f(n 1)  3•f(n  2) f(2) = 4•f(2 1)  3•f(2  2) f(2) = 4•f(1)  3•f(0) ^^ ^^ we already know these values to plug into the rule

Best ResponseYou've already chosen the best response.3wherever you see f(0), replace it by 5 wherever you see f(1), replace it by 20

Best ResponseYou've already chosen the best response.0f(2) = 4•f(1)  3•f(0) =65 correct?

Best ResponseYou've already chosen the best response.3so what we are looking for is a sequence that starts out: f(0), f(1), f(2) 5, 20, 65 only one of the options starts out like this
