Given three numbers A, B and C

B is A squared plus 1
C is B doubled

It could be a coincidence, seemed to easy.

there is also that the numbers in the first column add up by one. the numbers in the second column starting at 5 add up going 5, 7,9...and the third column has the numbers starting by adding 10 going up by additions of 4, so adding 14,18,22... this doesn't go by row, but it works going downward
