My question is: Joey needs to take a new prescription. The first day he needs to take one pill. Each day he must take two more pills than the previous day. How many pills will he take in a week? Your thoughts:
For the second day he takes 1 + 2 = 3 pills. For the third day he takes 3 + 2 = 5 pills. For the fourth day he takes 5 + 2 = 7 pills. For the fifth day he takes 7 + 2 = 9 pills. For the sixth day he takes 9 + 2 = 11 pills. For the seventh day he takes 11 + 2 = 13 pills. For the entire week he takes a total of 1 + 3 + 5 + 7 + 9 + 11 + 13 = 49 pills. The final answer: 49.
