If the sum of three consecutive integers is 9, what are the integers?

Oct 26, 2016

Consecutive integers are $2$, $3$ and $4$

Explanation:

Let the consecutive integers be $x$, $x + 1$ and $x + 2$.

As their sum is $9$, we have

$x + x + 1 + x + 2 = 9$

or $3 x + 3 = 9$

or $3 x = 9 - 3 = 6$

Hence, x=6×1/3=2

and consecutive integers are $2$, $3$ and $4$.
