41

Explanation:

We let the first odd number be a
That means that the next two odd numbers are a+2 and a+4, as odd numbers spaced out by 2.

From the given information this means that:
a+a+2+a+4 = 129
3a+6=129
3a=123
a=41

But we know that a is the smallest of the three numbers, therefore the smallest of the three numbers is 41, followed by 43 and 45.

We can check this because 41+43+45=129
