If |x – 9/2| = 5/2, and if y is the median of a set of q consecutive integers, where q is odd, which of the following must be true?
I. xyq is odd
II. xy(q^2 + q) is even
III. x^2y^2q^2 is even Pick:
A) I only is true	B) II only is true	C) I and III	D) II and III	E) I, II, and III
given:   q is Odd   y is the median of odd numbers, hence y is Odd   x = solving the modulus you get 7 and 2. Hence x is Even or Odd   Therefore: q = O, y = O and x = O or E   Statement I = x*y*q = y*q*x = O x O x O/E = O x O/E = Odd or even. So False   Statement II = xy(q^2 + q) = O/E x O (O + O) = O/E x O(E) = O/E x E = Always Even. So true   Statement III. x^2y^2q^2 is even. E/O x O x O = Odd or even. Hence False.   Answer =II only is true.
