Mathmetical Calculation

[k1ngscorp1o]

Hey, I'm looking to for a calculation that allows me to put in a user rank and spits out the exp...

rank 1 - 50,000 - start (x2 for rank 2)

rank 2 - 100,000 x 2

rank 3 - 200,000 x 2

rank 4 - 400,000 x 2

rank 5 - 800,000 x 2

rank 6 - 1,600,000 x 2

rank 7 - 32,000,000 x 2

rank 8 - 64,000,000 x 2

rank 9 - 128,000,000 - End

The base EXP is 50k so thats rank 1 and it you do rank 1 times 2 it gives you rank 2 and if you do rank 2 times 3 it gives you rank 3. I'm looking for a mathematical equation to do this. Yea there are numerous ways to do this with php but I want an equation that does it. Does anyone know how?

50,000 * 2^(rank-1)
