Medium WebJul 31, 2016 · the summation of -2n - 3, from n equals 2 to 10 is the sum of the first 10 term minus the first term. Tn = -2n - 3 T1 = -2 (1) - 3 = -2 - 3 = -5 T10 = -2 (10) - 3 = -20 - 3 = -23 Sn = n/2 (T1 + Tn) S10 = 10/2 (-5 + (-23)) = 5 (-5 - 23) = 5 (-28) = -140 Therefore, the summation of -2n - 3, from n equals 2 to 10 = -140 - (-5) = -140 + 5 = -135.
