    Hi guys,

    Question is above. I've solved the difference equation fine - I am however stumped on the last part.

    It's quite strange to find something that resembles number theory in a DE question! Any ideas on what to do is appreciated.

    Thanks.

    Hi guys,

    Since it says "hence", it's going to be dependent on the first part. What was the solution to the first part?
