A class writes the equation n+n+1+n+2=87 to solve the following problem.

The sum of 3 consecutive odd integers is 87. Find the three integers.

What error did they make?

I don't know where to start. I'm confused, I need help!!!

Help will be greatly appreciated.

  • Mathematics -

    the first thing is to find the three numbers, one problem is the variables are all the same if you need the numbers the formula is x+(x+2)+(x+3)=87

  • Mathematics -

    The problem is that they have written 3 consecutive numbers, not 3 consecutive ODD numbers.
    If the first number is n then the next odd number is n+2, because odd numbers are two apart.

    So the equation should have been

    n + n+2 + m+4 = 87

    Solve that one.
