'You're looking at it from the wrong angle'
I agree, it is about perspective.
I overcomplicated it. Tried to spot a sequnce, added up differences, subtracted every third term, took the swaure of each term and subtracted 4, ran out of fingers to add up on, tried pumping the numbers into a binomial model and when that failed, looked up the General Theory of Relativity to see if that could help shed light on it. When I found out that turning the paper upside down solved it, I decided a stiff drink was in order and that it was stupid anyway.
