CSEC Additional Mathematics: Lesson 034 - Finite Series

In this lesson, we continue the topic of Sequences and Series by examining how to find the sum of a finite arithmetic series and a finite geometric series. Students will learn how the formulae for these finite sums are derived and how they can be used to calculate the sum to a given number of terms. We will learn how to: • derive the formula for the sum of a finite arithmetic series; • use the first term, common difference and number of terms to calculate an arithmetic sum; • use the first and last terms to calculate the sum of an arithmetic series; • derive the formula for the sum of a finite geometric series; • identify the first term, common ratio and number of terms in a geometric series; and • calculate the sum of a finite geometric series.
