EXAMPLE

Fill a 3 x 3 matrix line by line from top row at the left with the numbers of the sequence in order:
19 10 9 19 1+9 19(1+9)
49 13 36 Equivalent to 49 4+9 49(4+9)
89 17 72 89 8+9 89(8+9)
So second column elements can be obtained as the sum of digits from the first column of numbers. Third column is the difference between the first two ones.
