I'm guessing 126 since this pattern looks like n^3 +1 where n= 0,1,2,3,4,...
Find the next number in the series. 1, 2, 9, 28, 65,?
Second differences seem to increase by 6 each time. Thus the series can be described by a 3rd order polynomial.
The next second difference will be 24, so the next first difference will be 61, and the next number will be 126.
The next second difference will be 24, so the next first difference will be 61, and the next number will be 126.
The next number in this series is 126.
Because, n^3+1 where, n=0,1,2,3,4,5...
