Which of the following sequences is defined by this recursive function?
5, 20, 65, 200, …
5, 20, 92, 372, …
5, 24, 92, 372, …

yes, so they give you the first one what is the second term?

we 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

we 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

wherever you see f(0), replace it by 5 wherever you see f(1), replace it by 20

very good :)

amistre64 Group TitleBest ResponseYou've already chosen the best response.1
so 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
