Sequence question... Can anyone help please? 10 pts?
Okay, I have a practice questions I need help with to study for my exam. It deals with a defined sequence.
We define the sequence like this (where "_" means subscript) :
S_n = 2*S_(n-1) + S_(n-2) - S_(n-3)
S_0 = 1
S_1 = 2
S_3 = 5
The question I need to do is:
Prove: " S_n > 2^(n+1) " for n > 4
--------------------------------------…
I know that I need to substitute the formula for both sides, but I'm really confused how to prove this. Do I have to use induction? Can anyone help? Thanks!
