# What are 3 consecutive odd numbers whose sum is 81?

Feb 1, 2016

$25 , 27 , 29$

#### Explanation:

If the first number is $x$, then the second number is $x + 2$ and the third number is $x + 4$. An example is $3 , 5 , 7$

$x + \left(x + 2\right) + \left(x + 4\right) = 81$

$3 x + 6 = 81$

$x = \frac{81 - 6}{3} = \frac{75}{3} = 25$

Therefore the numbers are $25 , 27 , 29$
