You can put this solution on YOUR website! What is the pattern in the numbers 1,4,10,20,35,56,84? I have tried to multiply numerous number but, I alas can't get it.
------
I ran a Cubic Regression Program on the data and got
the following equation:
y = (15/90)x^3 + (1/2)x^2 : (1/3)x
-------
I would not expect you could ever do that manually.
