**Kate**, Thursday, May 7, 2009 at 6:45pmS = 11 + 18 + 27 + 38 + 51 + 65 + 82 + .........+Tn

S = 11 + 18 + 27 + 38 + 51 + 65 + ................ + Tn

--------------------------------------...

0 = 11 + (7 + 9 + 11 + 13 + ....(n-1).terms.................) - Tn

0 = 11 + (n - 1)/2 [14 + 2(n - 2)] = 11 + (n - 1)(n + 5) - Tn

Tn = n^2 + 4n + 6. The given series in sigma notation is as follows.

SIGMA[k^2 + 4k + 6] the lower limit being k = 1 and the upper limit k = n
