$U \cap N = \left\{1, 3, 5, 7, 9, 11, 13\right\}$
The symbol $\cap$ represents intersection of sets. The intersection of sets U and N is the set that contains the common elements of U and N. The elements common to U and N are: 1, 3, 5, 7, 9, 11, 13 Thus, $U \cap N = \left\{1, 3, 5, 7, 9, 11, 13\right\}$.
