# Finding next experience level using the square root?

I recently asked this question on how to calculate a level based on experience:

Algorithm for dynamically calculating a level based on experience points?

I am using the following calculation to determine the players level:

decimal experience = 1829;
decimal rawLevel = (decimal)(.06 * Math.Sqrt(experience));
decimal level = Math.Floor(rawLevel);


For my test, 1829 experience points equates to 2.56600857364117M, which I floor to level 2.

My question is, how can I figure out how many points it would take to get to the next level based off of the calculation above?

I know the next level is 3, so I would need to figure out how many points equate to level 3 so that I can find the difference. What formula would I use, given the constant .06 above?

Update: Solution:

int experience = 150777;
decimal rawLevel = (decimal)(.06 * Math.Sqrt(experience));
decimal level = Math.Floor(rawLevel);
decimal nextPoints = (decimal)Math.Pow((double)(level + 1) / 0.06, 2);


Exp = (Level / 0.06)²
