Find two consecutive integers Whose sum is 61. See if you can write an equation to solve this problem… Define a variable. Write an equation. Solve it.

Consecutive Integer Problems* Example 4, page 94. Find three consecutive integers whose sum is -42. 4A: Find three consecutive integers whose sum is 21.

Formula for consecutive integers* For two consecutive integers: n + (n + 1) = 2n + 1 For three consecutive integers: n + (n + 1) + (n + 2) = 3n + 3 For four consecutive integers: n + (n + 1) + (n + 2) + (n + 3) = 4n + 6

Formula for consecutive odd or even integers* For two even or odd integers: n + (n + 2) = 2n + 2 For three even or odd integers: n + (n + 2) + (n + 4) = 3n + 6 For four consecutive even or odd integers: n + (n + 2) + (n + 4) + (n + 6) = 4n + 12
