Anytime you have a consecutive number word problem you need to set it up like this:
If the numbers are consecutive:
First Number: X
Second Number: X+ 1
Third Number: X+2
Fourth Number: X+3
and so on....
For example:
The sum of 4 consecutive numbers is 29, what are the numbers?
Set up the problem:
First is X, second is X+ 1, third X + 2, and fourth is X + 3
X + X+1+ X+ 2+ X+ 3=28
4X + 5= 28
4X=29-5
4X= 24
X=6
My numbers are 6,7,8 and 9
If they ask you for Odd or Even consecutive numbers
First: X
Second: X + 2
Third: X + 4
Fourth: X + 6
and so on ....
