<PRE><B>Question 155130</B>
I need to know what number comes next in this sequence and why.
9,73,241,561,1081,1849,_?__
-----------------------------
I matched 1,2,3,...,6 up with the numbers.
I tried a linear regression, a quadratic regression,
and a cubic regression on it.  Best results were 
with the cubic:
y = 8x^3 + 4x^2 -4x  = 1
-----------------------------
The next term would be f(7) = 2913
========================================
Cheers,
Stan H.
