Level System Formula

I was trying to get a level system for my game, I'm just not very great with it. I've been able to get formulas, but there not as 'clean'/'accurate' as I'd like them to be.

I do programming, not math! Which isn't great for a programmer, =) Shame my math man vanished from working on the game. oh well..

Anyways, the game consists of level 1 to 100, start leveling at level 2 basicly. I'm trying to get formulas that match or come close to these.

1 = 0
10 = 5,000
20 = 10,000
30 = 50,000
40 = 200,000
50 = 500,000
60 = 1,000,000
70 = 10,000,000
80 = 50,000,000
90 = 100,000,000
100 = 250,000,000

Does anyone have a clue, or is a complete genious on getting proper leveling numbers? Thanks!

Looks like an exponential function to me.

From a graping calculator's exponential regression I get y = 112.5319895*1.171763465^X

it is an ok representation of the data.
