Question 128214
Let's say the first odd number is x

So the next odd number after it is x+2

And the next one after that is x + 2 + 2


Add them up :  x + x + 2 + x + 2 + 2 = 39

Simplify it a bit :  3x + 6 = 39

So : 3x = 33 which means x is 11.

So the three consecutive numbers are 11, 13 and 15.
