18 Ιαν 2021 · The number of pairs would be this number divided by 2. You will notice that the size of the pair is the number of pairs plus 1. So, we could write use n to write (number of pairs) x (sum of each pair) = n/2 x (n +1) But remember, like before, we only want the sum of one row, not both. So we divide the formula above by 2 and get:
