V is the set of all odd numbers and can be represented by a large circle. A smaller circle, U, inside circle V, represents a subset of the odd numbers { 1 3 5 7 9 11 }. W is another circle, the given set of numbers, that intersects or interlocks with U within V, and the intersection region contains only the number 5. Each element of U is related to each element of W by the multiplier 5.
