How can I determine the percentage of entries which are even in a Sierpinski Triangle?

I know that the even numbers of pascal's triangle form the Sierpinski Triangle. I also know that as we add more columns (or rows) depending on how you look at it, the even numbers cluster together. I have this picture:

Am I correct in assuming this is basically Pascal's triangle and that the even numbers are the black squares and that the odd numbers are the even squares?



My actual question is: How can I come up with a formula that gives the percentage of entries which are even based off the number of columns which are in the triangle.



I have this table where the left column gives the number of columns in the triangle while the right columns gives the percentage of entries which are even.



7                25.

15 40.4412

31 53.9773

63 64.9519

127 73.5102

255 80.0553

511 85.0123

1023 88.7483


My approach would be to use the finite differences method to generate a polynomial but I don't think that would be appropriate since it would only give me one of many polynomials that it could be.



My final goal would be to implement this in Mathematica
