#32This question is not well-defined. Any number can be a solution.
It's defined just well enough to identify you as someone who'd rather debate the problem than attack it. In other words, it has done its job.

Here's one interpretation: What will the simplest program that outputs these numbers output next?

#37I discovered difference tables as a kid, didn't know they were used much, I was modelling motion on a 2D display (an oscilloscope hooked to a P2P11!). Was a lifesaver for quick polynomial evolution - uses only addition, execution time scales linearly with the order of the polynomial. So, how do you go from the difference table "coefficients" to the polynomial?
48 -> 48x -> 24x^2 -> 8x^3
Subtract 8x^3 from the series 9 - 8•1^3, 73 - 8•2^3, 241 - 8•3^3
and repeat the whole process on this series for the coefficient of x^2, etc...Re: 9,73,241,561,1081,1849,_?_

The simplest program that outputs these numbers is the program that outputs these numbers, so it doesn't output anything next.
python -c 'print 9,73,241,561,1081,1849
# or better yet

#40...1081,1849,[1890.067],[2248.467].... Now I just wonder how excel got these answers :/
