Let the first even integer be n.
Then the second consecutive even integer would be n%2B2
We must solve for n when:
n%2B%28n%2B2%29=18
n%2Bn%2B2=18
2n=18-2
2n=16
n=8->the first even integer
n%2B2=10->the second consecutive even integer

Find two consecutive even integers whose sum is 18
Middle integer or MEAN integer = matrix%281%2C3%2C+18%2F2%2C+or%2C+9%29
With 9 being the MIDDLE INTEGER, the EVEN INTEGERS are: highlight_green%28matrix%281%2C3%2C+8%2C+and%2C+10%29%29
