I’d like to ask the good people of this community that, if you do know the solution or figure it out, that you not share the answer here. Feel free to announce your success, but there’s something to be said for discovering the answer completely unaided, even if it takes years.
It’s embarrassingly obvious once you see it though.

That’s what I thought too, but it doesn’t work for the 7 at the end, and the caption explicitly says that the seven is not an error.
I’m not sure that strategy works for the last numbers.
Thats wrong, the last number in the line doesn’t follow that rule.
