Question

The sum of $3$ consecutive numbers is $27$. Find all the numbers.

Answer 1

Finding the numbers:

Let the $3$ consecutive numbers be $x-1,x,x+1$.

Now, the sum of $3$ consecutive numbers is $27$.

$\therefore$$$\begin{gathered} x-1+x+x+1=27 \\ 3x=27 \\ x=\frac{27}{3} \\ x=9 \end{gathered}$$

$$\begin{gathered} x-1=9-1=8 \\ x=9 \\ x+1=9+1=10 \end{gathered}$$

Thus, $8,9,10$ are the $3$ consecutive numbers whose sum is $27$.
