dont know why they had to make n the middle number....

3 consecutive even integers...n - 2, n, n + 2

so ur expression is : (n - 2 + n + n + 2) or simplify it a bit... 3n

The expression for the sum of these integers is 3n

Let the first number be n-2

Let the middle number be n

Let the third number be n+2

The expression for the sum of these integers will be:

=(n - 2) + n + (n + 2)

= n - 2 + n + n + 2

Collect like terms

= 3n

The expression for the sum of these integers is 3n
