Judging by this, the first part of the overall equation for a 3 step stair is 6n +?
This shows the difference between 6n and T as + 44
Therefore the equation for a 3 step stair on a 10x10 grid is 6n + 44
The same sequence can be used for a 4 step stair
Therefore the equation for a 4 step stair on a 10x10 grid is 10n + 110
Following the same sequence you find that the equation for a 5 step stair is 15n + 220, 6 stair ...
