If s is the sum of consecutive even integers w, x, y, and z,
where w < x < y < z, all of the following must be true
(A) z - w = 3(y - x)
(B) s is divisible by 8
(C) The average of w, x, y, and z is odd
(D) s is divisible by 4
(E) w + x + 8 = y + z
Just assume that the numbers are 2a, 2a+2, 2a+4 and 2a+6.
s = 2a + 2a+2 + 2a+4 + 2a+6 = 8a + 12
Focus on the easiest options first. You see that s is not divisible by 8. Answer (B)
Or you can take values: w = 0, x = 2, y = 4, z = 6. Their sum is 12 = s.
