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#
