http://www.mindbites.com/lesson/5116-series-arithmetic-series-455 This 68 minute sequences & series lesson begins with the terminology of a series and will show you how to use the general sum formula to find the sum of an arithmetic series as well as how to: - tell the difference between an arithmetic sequence and an arithmetic series - find the first term - find the common difference - find the number of terms - use the last term formula - use a system of equations to solve problems Sample question: A movie theatre has 40 rows of seats. Each row has three more seats than the previous row. If there are a total of 4140 seats in the theatre, how many seats are there in the first row? This lesson contains explanations of the concepts and 15 example questions with step by step solutions plus 7 interactive review questions with solutions.
