In cell A11 I have a formula that counts the number of records on a different spreadsheet. In cell B11 I have an account number from a Vlookup. I would like to take the number in B11 and add 1 to it (for example if B11 is 2100 then B12 would be 2101, and B13 would be 2102, etc). I would like for this formula to run as long as the number in cell A11. For example if A11 is 4 and B11 is 2100 then it will add down three more times so B12 is 2101, B13 is 2102, B14 is 2103.

Thank you in advance for the help.
