The pattern that Caleb saw is that the products in the first shaded row
for some factors are six times the products in the second shaded row for other
factors.
EXPLANATION
The relationships between the
factors in the two rows have an effect on the relationship between the products
of those factors. Therefore, since 6 is 6 times of 1, the products in the row
for 6 are six times the products in the row for 1.
