Question

Look at these numbers.

4, 7, 10, 13

Which pair of numbers has an odd product and an even sum?

Answer 1

Two numbers will multiply out to an odd number if both are odd.

Likewise, if both numbers are odd, then they add up to an even number.


So for instance, 7 is odd and 13 is odd. So 7*13 = 91 (which is odd) and 7+13=20 (which is even)

Answer 2

So 7 and 13 would be the correct answer? correct?

Answer 3

yer right!

Answer 4
