Sum of n first numbers
WebAs usual, the first n in the table is zero, which isn't a natural number. Because Δ 3 is a constant, the sum is a cubic of the form an 3 +bn 2 +cn+d, [1.0] and we can find the coefficients using simultaneous equations, which we can make as we wish, as we know how to add squares to the table and to sum them, even if we don't know the formula.
