What the product multiplies

What does the product multiply? The same values as the sum. For $x=$ ('$1$', 'FFD84A'), $\displaystyle 1 + 2 = 3$. For $x=$ ('$2$', 'FFD84A'), $\displaystyle 2 + 2 = 4$. For $x=$ ('$3$', 'FFD84A'), it is 5. For $x=$ ('$4$', 'FFD84A'), it is 6. For $x=$ ('$5$', 'FFD84A'), it is 7. This time the results are multiplied: The product is $\displaystyle 3 \times 4 \times 5 \times 6 \times 7 = 2520$. And In steps of 2, $\displaystyle x$ is 1, 3 and 5: $\displaystyle 3 \times 5 \times 7 = 105$.
