Series of incrementing numbers

New to mockaroo, so not sure if this is something I can do…

I’d like to simulate the series of incrementing numbers representing “units sold so far today” or “visitors in the store today” or “client transactions today”.

The sequence only allows a fixed step counter rather than some number that varies per row.

Is there a way to sum a column? Or write a formula that references values in a prior row?

It would make no sense to have values that pull back from one row to the next.
