Properties of Summation and Summation Formulas When evaluating a sum written in sigma notation, it is often easier to rewrite the sum using the properties below:

Summation formulas We can derive the following summation formulas: ∑ i = 1 n c = c + c + + c + c = n c here, c is a constant. ∑ i = 1 n i = 1 + 2 + + (n 1) + n = n 2 (n + 1) The last equation follows from …

Answer to: Use the properties of summation and summation formulas (Theorem 4.2) to evaluate the sum. Use the evaluation to find the limit as n...
