1 Answer

Jul 5, 2018

$19$ $19$ and $21$ $21$

Explanation:

Let $n$ $n$ be a odd integer

Then $n + 2$ $n+2$ would be the consecutive odd integer after $n$ $n$ :

The sum of these is 40:
$n + (n + 2) = 40$ $n+(n+2)=40$
$2 n + 2 = 40$ $2n+2=40$
$2 n = 38$ $2n=38$
$n = 19$ $n=19$
$n + 2 = 21$ $n+2=21$
