Problem 4 Part 1. Consider the recurrence relation an = 4an-1 4an-2.

a. Find the general solution to the recurrence relation (beware the repeated root).

b. Find the solution when a0 = 1 and a1= 2.

c. Find the solution when a0 = 1 and a1 = 8.

Part 2. Suppose that rn and qn are both solutions to a recurrence relation of the form an = an-1 + an-2. Prove that c rn + d qn is also a solution to the recurrence relation, for any constants c, d.
