@medoyia 2nd
7=14
6=18
5=20
4=22
3=24
Could be a chance that first column is descending by 1 but 2nd is ascending by 2 and again 4 is not here buts still exists
So 15 or 24
@medoyia I have 2
1st
7x2=14
6×3=18
5×4=20
4x5=20
3x6=18 first column is descending 7 to 3 and the other is ascending 2 to maybe 5 but 4 is not here but it doesn't mean it doesn't exist
