How to create incremeneted Check Number in Access table from a specified starting check number.

Hi, I'm trying to create a module or some type of formula that will prompt the user to enter a beginning check number:  i.e. 1118172 and then update subsequent rows in a table with sequential number including that first number, incremented by 1 for each subsequent line.  

Here is an example...

Starting Check Number:  1118712
First three rows in the table would have:

1118712
1118713
1118714

I have a column in a table labeled:  RFCK#.  I would like to use some form of a parameter value to enter the first check number and then cascade down, as I described above.  I've tried many things, but it is just getting frustrating.

Any help on this would be greatly appreciated.
