If you are trying to say that the commons difference is an integer, then we know it is positive, and divides 73-37=36

so, the difference may be 1,2,3,4,6,9,12,18

However, d must also divide 37-13=24

and 73-13=60

That narrows our choices to 1,2,3,4,6,12

d T100

1 13+1*99=112

2 13+2*99=211

3 and so on
