How come D is not the answer if we apply 3+5/2=4 , therefore even?

If positive integers a and b are both odd, which of the following must not be odd?
A. ab
B. a(ab)
C. b – a – 1
D. (a + b)/2
E. a – b
A. ab
B. a(ab)
C. b – a – 1
D. (a + b)/2
E. a – b
Good observation, thats why I mentioned the result of (D) may/may not beEVEN

D. ODD + ODD = EVEN/2 = EVEN/ODD
You have considered the numbers as 3 and 5 , see if I take the numbers as 1 and 5
\( \frac{(a + b)}{2} =\frac{6}{2} = 3 (ODD) \)
