  pair sums to twice the average and therefore that the sum is the number of terms times the average term. Here is an example in a particular case and then the general formula. Example: Evaluate ￿29 n=13 n. There are 17 terms and the average is 21, which can be computed by averaging the first and last terms: (13 + 29)/2=21. Therefore,the
