If a, b, and c are consecutive positive even integers and a > b > c, which of the following could be equal to a - b - c ?
Choose the correct choice from the following answers:  A) 6  B) 2  C) -1  D) -3  E) -4
a = 2n (n&gt;=3), b = 2n - 2, c = 2n - 4   a -b -c = 2n - (2n-2) - (2n-4) = 6 - 2n &lt;= 0   since n &gt;=3 ,   even -&gt; -4   ANSW-4R:-4
