The second digit of each number set is the sum of the second digits from the two previous sets of numbers. For example... 43 and 23 (3+3=6), which makes the second digit of the next set of numbers a 6 (46).
The first digit of each number set in the sequence of numbers, is the same as two sets prior, with the exception of needing to increase the first digit by one when “carrying over”.
For example... The first digits stay in rotation of 4, 2, 4, 2, except 58, because when adding the 6+9 (from the third and forth set of numbers), you have 15, which requires the 1 to be carried over to the first digit (4), which gives you 58.
It’s a long shot, but I tried😋
