Math Problem Statement

The sum of three consecutive odd integers is 69. What are the three integers?

Solution

The problem asks for three consecutive odd integers whose sum is 69.

Solution:

  1. Let the first odd integer be xx.

  2. The next consecutive odd integers are x+2x + 2 and x+4x + 4.

  3. The sum of these three integers is given as: x+(x+2)+(x+4)=69x + (x + 2) + (x + 4) = 69

  4. Simplify the equation: 3x+6=693x + 6 = 69

  5. Subtract 6 from both sides: 3x=633x = 63

  6. Divide by 3: x=21x = 21

Thus, the three integers are: 21,23,and 2521, 23, \text{and } 25

Final Answer:

The three consecutive odd integers are 21, 23, and 25.
