Homework Statement
The sequence [tex]f_n[/tex] is defined by [tex]f_0=f_1=2[/tex] and
[tex]f_n = (\frac{f_{n-1}+2f_{n-2}}{6})[/tex], when [tex]n\geq2[/tex].
Find a non-recursive formula for [tex]f_n[/tex]
The Attempt at a Solution
Well I have solved for the closed formula of the generating function which I will call g(x) so
[tex]
g(x) = \frac{12-10x}{6-x-2x^2}
[/tex]
My question is, is this what they are looking for or do I need to continue and use partial fractions and linear algebra to get farther?
