.
The sum of three consecutive odd numbers is 51
~~~~~~~~~~~~~~~
Let the numbers be (x-2), x, (x+2).
Then the sum is (x-2) + x + (x+2) = 3x.
The equation is 3x = 51.
The solution is x = 51/3 = 17.
The ANSWER is: the numbers are 15, 17, 19.
The lesson to learn: the sum of three consecutive odd integer numbers is thrice the middle number.
The other lesson to learn: if the sum of three consecutive odd integer numbers is given, then the middle number is one third of the sum.
Happy learning (!)
