The sum of three consecutive even numbers is 28..

Let consecutive even number x, x + 2, x + 4 $\begin{array}{l}\text{According to the question,}\\ \text{(x + x + 2 + x + 4) – }\frac{\left(\text{x + x + 2 + x + 4}\right)}{3}\\ \begin{array}{l}\left[\Large\frac{3(3x+6)-(3x+6)}{3}\right]=28\\ 2(3x+6)=28\times3\\ 3x+6=42\\ 3x=36\\ x=12\\ \text{ So, smallest number }=\mathrm{x}=12\end{array}\end{array}$
