SEQUENCES AND SERIES
For example, 1 + 3 + 5 + 7 is a finite series with four terms. When we use the phrase “sum of a series,” we will mean the number that results from adding the terms, the sum of the series is 16. We now consider some examples. Example 1 Write the first three terms in each of the following sequences defined by the following: (i) an = 2n + 5 ...
