# Three consecutive natural numbers have a sum of 30. What is the least number?

Nov 28, 2016

The least number is $9$.

#### Explanation:

Considering the numbers as $x$, $\left(x + 1\right)$, and $\left(x + 2\right)$, we can write an equation:

$x + \left(x + 1\right) + \left(x + 2\right) = 30$

Open the brackets and simplify.

$x + x + 1 + x + 2 = 30$

$3 x + 3 = 30$

Subtract $3$ from each side.

$3 x = 27$

Divide both sides by $3$.

$x = 9$
