Answer

The numbers are 35 and 37.

Work Step by Step

Let n represent the first number; then, n + 2 represents the next odd number. Because their sum is 72, we can set up and solve the following equation: n + n + 2 = 72 2n + 2 = 72 Subtract 2 from both sides 2n = 70 n = 35 If n = 35, then n + 2 = 37 So, the numbers are 35 and 37
