You can put this solution on YOUR website!
Why does the equation n + (n+1) + (n+2) = 84
Since you do not know what the integers are you will make the first integer =n;
Now since they are consecutive, it means the next integer right after n, which would be n+1,
ex.
lets say 3 is our first integer, what is the next integer after 3? 4
What do you add to 3 to get 4? 3+1
The third integer would be? 3+2=5
So since you do not know the integers, you use a variable such as n.
n = first integer
n+1=second integer
n+2= third integer
Hope you understand
