Any of these is a rational number between 5.2 and 5.5.
n, n + 2 - two consecutive even integers
the sum of two consecutive even integers is greater than or equal to 34
n + (n + 2) ≥ 34
n + n + 2 ≥ 34
2n + 2 ≥ 34 <em>subtract 2 from both sides</em>
2n ≥ 32 <em>divide both sides by 2</em>
n ≥ 16
<h3>Answer: The smallest possible integers is equal 16.</h3>
