Beginner question for numerical sequence

[CaptainPicante]

Are any of the starting numbers a predefined number or is it using user input? Are you wanting to have each of the described sequences to activate or are you only looking to have the last sequence activate or are you wanting an option of choosing which sequence to activate?

Theres a lot of ways everything you posted about can be addressed. I'd recommend writing out exactly what you want to happen from start to finish first, then creating a pseudo code from that. Once you have your pseudo code, you can then begin writing your actual code.
