I'm assuming you cheated by searching for the terms...

Gotta admit, I'm a little bothered by the fact you precluded anyone from actually trying.

Perhaps you should state that you're issuing a math challenge and that you actually know what the answer is.

I'm issuing a math challenge.

I actually know what the answer is.

I'm curious how someone would deduce the answer to this. You'd have to convert to base 4 before you could see the actual sequence being used, right?

I, personally, would have to.

Sorry, I thought this was part of your research, and you wanted to know the answer. I didn't realize that this was a problem for the community.
