Best ResponseYou've already chosen the best response.1What do you have to do with this sequence?

Best ResponseYou've already chosen the best response.1Maybe it's clearer to write it as: \[a_n=a_{n1}+3a_{n2}\]\[a_0=1,a_1=2\]

Best ResponseYou've already chosen the best response.0im trying to figure it out because the way i keep solving it is apparently wrong by the book

Best ResponseYou've already chosen the best response.1Yes, I see that, but what is your question about it? Do you need terms of this sequence?

Best ResponseYou've already chosen the best response.0yes how do you solve it

Best ResponseYou've already chosen the best response.1It says: If you want to know a certain number of this sequence, you need the two numbers before it. Take the last number and add 3 times the number before it to get the new one. That is why there are two start numbers given.\[a_2=a_1+3a_0\]\[a_3=a_2+3a_1\]So you can calculate every number in the sequence. I don't understand what you mean by solve it.

Best ResponseYou've already chosen the best response.0Okay so if i was to do it like that then .. a2 = 2 + 3(1) = 5 right?

Best ResponseYou've already chosen the best response.0is that right or wrong because my book says im wrong

Best ResponseYou've already chosen the best response.1You are, because it is 5 + 3*2 = 11

Best ResponseYou've already chosen the best response.0lol i never took into consideration a0 and a1 as being apart of the answer so i was so confused as to how they got 1,2,5, then 11 lol

Best ResponseYou've already chosen the best response.1So a4 = 11 + 3*5 = 26 a5= 26 + 3*11 = 59 etc.

Best ResponseYou've already chosen the best response.1YW! a0 and a1 are needed to give you a way to "start up"..
