Quandaries
and Queries 

It's a real challenge. I actually got the answer, but I guessed the system, I didn't calculate it, because I couldn't. So I thought it was a little unfair of him, since I don't think it's possible to calculate your way to the solution. Is there a way to calculate this puzzle? Or can the solution only be  "x" and "y" each represents a number. I will provide the solution in a .txt document, so you can have them Yours sincerely 

Hi Lasse, There isn't a way to "calculate" the system in the way you are thinking since there is more than one solution. In any of these questions, where you are given a few terms in a sequence and asked for the next erm or a rule to calculate the next term, there is alwys more than one solution. Penny
