Katie is a stockbroker. During a 100-day span of trading stocks she continued a certain pattern. On day 1 she started out by losing $100. Every day after the first day, she loses $100 more more than the previous day. What is the average daily loss during the 100-day period?

What have you tried? Have you learned about sequences and series? Have you listed the first few days' losses, and found a pattern? Have you figured out the first and last days' losses?
