2 + 4 + 6 + 8 + :::+ 22 + 24 notice that we can factor a 2 out of each term to rewrite this sum as 2 1 + 2 2 + 2 3 + 2 4 + :::+ 2 11 + 2 12 that means that we are adding together 2 times every number between 1 and 12. Any random sum, say 2 + 3 + 7 + 25 + 51, cannot be written using the sigma as we cannot find a general term in this case.

A Term Using Sigma Notation Is Called A Series Or Summation ( Sum For Short).

According to the notation in the problem, we are told to sum the results obtained by evaluating the equation at each integer between the numbers below and above the sigma. Xn i=m q i = q m + q m+1 + q m+2 + + q n: Integers i = m;m+1;m+2;:::;n, and we introduce a notation for the sum of all the q i for i = m to n:
