Ken wants to get more exercise so he begins by walking for 20 minutes. Each day for two weeks, he increases the length of time that he walks by 5 minutes. At the end of two weeks, the length of time that he has walked each day is given by the following arithmetic sequence: 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85 The total length of time that Ken has walked in two weeks is the sum of the terms of this arithmetic sequence: 20+ 25 +30 +35+ 40 + 45 + 50 + 55+60 +65 + 70 +75 + 80 +85 This sum is called a series.
