WebAug 18, 2014 · To see where the above comes from, note that S = 1 − 1 2 + 1 2 2 ⋯, and so − 1 2 S = − 1 2 + 1 2 2 ⋯. Hence we have the equation S = 1 − 1 2 S. (This is contingent on the series being convergent, otherwise one can end up with nonsense.) Share Cite Follow edited Aug 18, 2014 at 14:30 answered Aug 18, 2014 at 7:05 copper.hat 166k 9 101 242

WebAnother way to derive this formula is to let S = Sum from k to n of i, write this sum in two ways, add the equations, and finally divide both sides by 2. We have S = k + (k+1) + ... + (n-1) + n S = n + (n-1) + ... + (k+1) + k. When we add these equations, we get 2S on the left side, … WebLearn how to calculate summations involving a constant from 1 to N.
