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.
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
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.
