Examples: Write an equation and solve.
1: Find three consecutive integers with a sum of 60. 2: Find three consecutive odd integers with a sum of 57. 3: Find four consecutive negative odd integers such that the product of 4 and the third is four less than the sum of the first and last. Essential Questions: 1. Why does an equation to find consecutive odd integers look like an equation to find consecutive even integers?
2. Can the sum of two consecutive even numbers equal the sum of two consecutive odd numbers? 3
