The three consecutive odd integers are 23, 25, 27.

Explanation:

Let x be the first odd integer
So,
x+2 is the second odd integer
x+4 is the third odd integer

Let's us translate the given expression into algebraic expression:
sum of the first and the third integer equals the sum of the second and 25
that means :
if we add the first and third integer that is :x+(x+4)
equals to the sum of the second and 25: =(x+2)+25

The equation will be stated as:

x+x+4=x+2+25
2x+4=x+27
Solving the equation we have:
2x-x=27-4
x=23

So the first odd integer is 23
The second integer will be x+2=25
The third integer is x+4=27

So the three consecutive odd integers are:23 ,25 ,27.
