Queries :: Append Query For Temp Table

I am trying to create a table from a form. The form has several fields but I need to take the value from 4 separate combo boxes ([cr] +[br] +[tr] and add them, then add the value from one more combo box [inc] to be my beginning value in a table.

I then need to add the last value [inc] to the total and that become the next line in the table. I would the like to add this value [inc] an infinite number of times until it reaches a max number.

The scenario would be something like this
cr=3 br=2 tr=3 inc=1.5

So the first total would be 9.5. Then every row after that would be plus 1.5
11
12.5
14
15.5
17
and so on.

This would be a temp table that I would run a query on to let an operator know lengths they can choose from in a combo box. I don't know if this is even possible.
