Summation factorial
Web15 Jul 2007 · Well if n is even we can easily see the number of pairs is n/2. However is n is an Odd number, then the number of pairs that add up to (n+1) is (n-1)/2. And we still have a term in the middle, and we can see that one is (n+1)/2. Simple algebra gives the same sum : n (n+1)/2. Jul 15, 2007. WebThis is a fairly common pattern of manipulation.
