SUMMARY

The discussion centers around the mathematical sequence that begins with the numbers 1, 5, 9, 101, 1385, 3493, 30121, and 358885. A user references the Online Encyclopedia of Integer Sequences (OEIS) entry A098097, which provides context for the sequence. The conversation highlights the necessity of converting the sequence to base 4 to deduce the next number accurately. Participants express frustration over the challenge's presentation and the need for clarity regarding the problem's intent.

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.
 
how about this one, what's the next number?

1, 2, 42, 24024, ...
