Exploring Quick addition When Carl Gauss was young, around 7 years old, his teacher asked him to add all the numbers from 1 to 100 to keep him busy. His teacher was amazed when the young boy gave him an answer very quickly. Can you do the same thing by determining the sum of the following arithmetic sequence as quickly as possible? a. 2, 4, 6, 8, 10, 12, 14, 16, 18 b. 3, 6, 9, 12, 15, 18, 21, 24, 27 c. 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 1. How much time did you spend in determining the sum of the terms? 2. Were you able to find a pattern to quickly add the terms? 3. If you were able to get a pattern, can you add all the numbers in an arithmetic sequence divisible by 10 from 10 to 1000 quickly
