The 2 columns of numbers have thier differences that follow fibonaci sequence with the 1st column starting with differences 6 and 5 and 2nd column starting with numbers -1 and 6

The 3rd difference for 1st column should be 6+5 = 11

And for 2nd column -1 + 6 = 5.

Similarly the last difference for 1st column is 16 + 11 = 27

And for 2nd column it's 11 + 5 = 16

So the 1st column answer = 27 + 46 = 73

And the 2nd column answer = 16 + 32 = 48.
