let x be the first integer, the next odd integer is %28x%2B2%29, the next one is %28x%2B4%29
The sum of three consecutive odd integers is x%2B%28x%2B2%29%2B%28x%2B4%29
the equation is
x%2B%28x%2B2%29%2B%28x%2B4%29=69
x%2Bx%2B2%2Bx%2B4=69
3x=69-6
3x=63
x=63%2F3
x=21 is the first integer
x%2B2=21%2B2=23, x%2B4=21%2B4=25
Check the answer: 21%2B23%2B25=69 - correct
Answer: 21, 23, 25
