Answer:
See proof below
Step-by-step explanation:
We have to verify that if we substitute  in the equation
 in the equation  the equality is true.
 the equality is true.
Let's substitute first in the right hand side:

Now we use the distributive laws. Also, note that  (this also works when the power is n-2).
 (this also works when the power is n-2).



then the sequence solves the recurrence relation.
