Make a conjecture about the product of an even and an odd number based on the following pattern: 2 = 2 x 1
6 = 3 x 2
30 = 5 x 6
56 = 7 x 8
90 = 9 x 10
and so on.
The product of an even and an odd number is equal to the square of the odd factor.
The product of an even and an odd number is equal to the sum of the factors.
The product of an even and an odd number is an even number.
The product of an even and an odd number is a prime number.
