What do you have to do with this sequence?

Maybe it's clearer to write it as: \[a_n=a_{n1}+3a_{n2}\]\[a_0=1,a_1=2\]

Yes, I see that, but what is your question about it? Do you need terms of this sequence?

yes how do you solve it

It 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.

Okay so if i was to do it like that then .. a2 = 2 + 3(1) = 5 right?

Sceptre12 Group TitleBest ResponseYou've already chosen the best response.0
and a3 = 5 + 2 = 7

is that right or wrong because my book says im wrong

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

lol 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
 one year ago

So a4 = 11 + 3*5 = 26 a5= 26 + 3*11 = 59 etc.
