------------
The equation is:
n + n+2 + n+4 = 39
------------
That's the hard way, tho.
Get the average, = 39/3 = 13
That's the middle number
--> 11, 13, 15

You can put this solution on YOUR website! Let x,,,,,x+2,,,,,x+4,,,,be consecutive odd numbers
.
sum= (x) + (x+2) + (x+4)= 3x +6 = 39
.
3x=33
.
x=11
.
.
numbers are 11,13,15
.
.
check 11+13+15 = 39,,,,,,ok
