Answer:

  The smallest of the two consecutive integers is 10 or less.

Step-by-step explanation:

Let x represent the smallest of the even integers in the sequence.

Then the sum of two consecutive even integers is ...

  x + (x +2) = 2x +2

And half the sum of the next two consecutive even integers is ...

  (1/2)((x +4) + (x +6)) = x + 5

The relationship between these values is ...

  2x +2 ≤ 7 + (x +5)

Subtracting x+2 gives ...

  x ≤ 10

The least of the two consecutive even integers is at most 10.
