Answer:
Say one number = x
other number = x+1
their product = x(x+1)
=x^2+x
if x is odd then
x^2 is odd and odd +odd = even
=> x^2 + x is even.
If x is even
x^2 is even and even + even = even
=> x^2 + x is even
since all even numbers are divisible by 2
the product of two consecutive numbers is divisible by 2
