So I'm reviewing for an exam, and all the review question put up by the professor is as follows:

Solve.

We didn't really cover this in class, and the example in the book is less than adequate, so I"m not sure what to do.

It says that a recurrence relation of the fom

Is satisfied by the sequence if

For this problem A = 2 and B = 0, which would make the equation

t^2 - 2t = 0

t(t-2) = 0

So the roots would be t = 0 and t = 2. So the only solution would be the sequence 1, 2, 4, 16... and 1, 0, 0, ...

Is that correct?
