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 most appropriate option: A) 6 B) 2 C) -1 D) -3 E) -4
consectutive even , X , X + 2 , X + 4 where X = Even   now subtract X + (X+2) - (X+4)   doing this leaves us with X -2   what even number can we substitute in X to yield an answer choice   2 works 2 (plug in 4 for X)
