Final answer:
Node 2's pointer in a doubly-linked list points to node 3.
Step-by-step explanation:
In a doubly-linked list, each node contains two pointers: one pointing to the next node and one pointing to the previous node. Given a doubly-linked list (2,3,4,5,6,7), node 2's pointer(s) point(s) to node 3. In this case, node 2 points to the next node in the list, which is node 3.
