If it were arithmetic, then

2%2F30-1%2F20+=+3%2F40-2%2F30+=+4%2F50-3%2F40 or

cross%281%2F60+=+1%2F120+=+1%2F200%29

That's certainly false.

If it were geometric, then

%282%2F30%29%2F%281%2F20%29+=+%283%2F40%29%2F%282%2F30%29+=+%284%2F50%29%2F%283%2F40%29 or

cross%284%2F3+=+9%2F8+=+16%2F15%29

That's certainly false.

So it's neither.
