Expanding summation
WebExpanding the summation notation is just the opposite process of writing it. Here are the steps for writing the same. Substitute every value of the index (starting from the first to last and increasing it by 1 every time) in the general term. Place a plus symbol between all such terms obtained from the last step. WebS = 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, and n-k+1 column sums that …
