Three consecutive odd numbers add up to -267

If "x" represents the first odd number, then

"x+2" represents the second number

"x+4" represents the third number


x+(x+2)+(x+4)=-267

From this expression, you can calculate the value of x


\begin{gathered} x+x+x+2+4=-267 \\ 3x+6=-267 \end{gathered}

Pass 6 to the right side of the equation by subtracting it from both sides of the expression


\begin{gathered} 3x+6-6=-267-6 \\ 3x=-273 \end{gathered}

Finally divide both sides of the expression by 3 to determine the value of x


\begin{gathered} (3x)/(3)=-(273)/(3) \\ x=-91 \end{gathered}

Now that we know the first odd number you can calculate the other two as follows:


\begin{gathered} x=-91 \\ x+2=-91+2=-89 \\ x+4=-91+4=-87 \end{gathered}

The three odd numbers that add up to -267 are -91, -89, and -87
