(3) For every $n \in \mathbb{N}$, denote by $p_n$ the $n$-th prime number, and let $g_n = p_{n+1} - p_n$. (i) Show that $\lim \sup_{n \to \infty} g_n = \infty$. (ii) Let $A = \{n \in \mathbb{N} : n, n+2 \text{ are prime}\}$. Show that $\lim \inf_{n \to \infty} g_n = 2$ if A is infinite, whereas $\lim \inf_{n \to \infty} g_n \ge 4$ if A is finite. Hints: In (i), consider the numbers $n! + j$ for $j = 2, 3, \dots, n$; in (ii), note that $g_n$ is even for all $n \ge 2$.
