Creating a Recursive Formula in a single cell?

I have searched Google and stack exchange extensively and cannot find a solution that fits my needs.

I have a recursive formula in a Google Spreadsheet that can be represented as

F(0) = 0F(1) = 5000F(n) = F(n-1) + ((n-1) * 5000)

I can effectively calculate this with a long two column table with n values in column A and the recursive formula in column B which references the previous cell when needing to access F(n-1).

This approach is clunky, takes up space, and requires a separate table for every different calculation. In my sheet I need to calculate this formula for different values of F(0) and it requires a separate table for each one.

What I want is a simple single cell with a formula that references another cell for the n value and calculates the result recursively all in the background, instead of taking up a whole set of space in a table somewhere in my sheet for it to do the recursion through multiple cells.

My spreadsheet to make it clearer:

Is this possible?
