Write an equation and solve each problem. Find three consecutive odd integers with a sum of 75.
62/87,21
Let n = the least odd integer. Then n + 2 = the next greater odd integer, and n + 4 = the greatest of the three integers. The sum of the three consecutive odd integers is 75. So, n + (n + 2) + (n + 4) = 75.

The integers are 23, 25, and 27.
Find three consecutive integers with a sum of ?36.
62/87,21 Let n = the least integer. Then n + 1 = the next greater integer, and n + 2 = the greatest of the three integers. The sum of the three consecutive integers is ?36. So, n + (n + 1) + (n + 2) = ?36.
The integers are ?13, ?12, and ?11.
