(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.

"Consecutive" means one after the other.

1,2,3,4,5,6... are consecutive integers while 1,4,5,6,10,15,20... are non consecutive integers.

I have answered your other post for "inclusive" integers at the location set-a-consists-of-the-integers-from-4-to-12-inclusive-while-set-b-202080.html#p1551976

Even numbers will always be a part of set of consecutive integers (set having more than 1 integers). Any odd integer is followed by an even integer.
