QUESTION 2
Consider the following:
ak = 2 ak-1+3ak-2
ao = 1,a1=2
Suppose a sequence of the form 1, x, x2, x3.....x".
... where X + O satisfies the given recurrence relation. Find all possible values of X. In other words solve the characteristic polynomial for X
. Enter your answers in a comma separated list:
Using the initial conditions and the values of X above, you can write the general solution as an= ar" + br, where r and r, are the answers to the first part of this question. What are the values
of a and b?
