Let three be (x - 1), x and (x + 1).
The sum of three consecutive number is x, means that
[tex]\begin{gathered} x-1+x+x+1=147 \\ 3x=147 \\ x=\frac{147}{3} \\ =49 \end{gathered}[/tex]The value of x is 49.
Determine the two numbers.
[tex]\begin{gathered} x-1=49-1 \\ =48 \end{gathered}[/tex][tex]\begin{gathered} x+1=49+1 \\ =50 \end{gathered}[/tex]So three consecutive numbers are 48, 49 and 50.
