5-6-7-2-1 appears to be regular sequence three times followed by 2-1 but I'm doubting it can really be that easy

it's 2, 3, 4

it goes up one more than before, and then goes 2, 1. so expanded it would be 1, 2, 3, 2, 1, 2, 3, 4, 2, 1, 2, 3, 4, 5, 2, 1, 2, 3, 4, 5, 6, 2, 1,...

So the next three would be 2, 3, 4

So the next three would be 2, 3, 4

that is also interesting sequence ... as to me,

I was thinking about the letters in Roman Numerals ...

So, it goes 1, 2, 3, 2, 1, 2, 3, 4, 2, 1, 2, 3, 4, 3, 2, 3, 4, 5, 3, 2, 3, 4,...
