Best ResponseYou've already chosen the best response.0look at the y's to figure out the pattern. What are they doing to get to the next number? Think in terms of addition and multiplication

Best ResponseYou've already chosen the best response.0right, so that's the answer to #1

Best ResponseYou've already chosen the best response.0For number 2 what it be f(x) = f(n1) x 2

Best ResponseYou've already chosen the best response.0For the recursive formula, the first thing is to write the first term. It looks like they're using function notations, so start with f(1). y is 5 when x is 1, so the first part is \[f(1)=5\] Then since it's multiplying by 2, \[f(n)=2f(n1)\]

Best ResponseYou've already chosen the best response.0So it would only be f(n)= 2f(n1)

Best ResponseYou've already chosen the best response.0no, you need to keep f(1) = 5 as well. The recursive formula only gives you a term if you know the previous term

Best ResponseYou've already chosen the best response.0so f(1)=5 2f(n1)

Best ResponseYou've already chosen the best response.0between 5 and 2 i don't put nothing ?

Best ResponseYou've already chosen the best response.0Write it like this \[f(1)=5, f(n)=2f(n1)\]

Best ResponseYou've already chosen the best response.0oh it was like that

Best ResponseYou've already chosen the best response.0It's saying that the first term is 5. Then to find the second term, multiply the first one by 2. Then to find the third term, multiply the second by 2. and so on. So with a recursive formula, if you want to know the 67th term, you have to know the 66th. But to know the 66th, you have to know the 65th and so on. It's only useful to point out the pattern. Not really useful for anything else

Best ResponseYou've already chosen the best response.0The explicit one is the useful one. \[f(n)=ar^{n1}\] a = first term r = number you multiply by (called the common ratio) Plug in your numbers to that formula to get the explicit formula

Best ResponseYou've already chosen the best response.0so i plug in 65?

Best ResponseYou've already chosen the best response.0no, your first term is 5, and you're multiplying by 2. So plug in 5 for a and 2 for r to get the formula

Best ResponseYou've already chosen the best response.0the function for A is geometric because it's multiplying by the same number to get to the next term.

wintersuntime

Best ResponseYou've already chosen the best response.0Isn't it geometric

Best ResponseYou've already chosen the best response.0I gtg. sorry I can't stay to help on the next one
