We need 2n - 2 50 host addresses. With n6 host bits, 26 - 2 62 hosts, which satisfies the requirement, giving a mask of 26 32-626. n5 27 gives only 25-230 hosts, which is insufficient. 25 n7 gives 126 hosts, which works but is not the smallest subnet that satisfies the requirement, making 26 the correct minimal choice.
