I am working on a section on undetermined coefficients of a difference. I'm really trying to understand the material, but am struggling.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]y_{n+1}[/tex]-2[tex]y_{n}[/tex]=2

I got as far as saying for the homogenous equation y=[tex]c_{1}[/tex][tex](-1)^{n}[/tex].

I'm assuming the guess next would be A, but I'm confused.

Maybe if someone could help me with some examples on how to do this using the 2 or something like 2^n or cos(n). I'm trying to learn something something new on my own and it's hard.
