To find the 4th landmark number in a base-7 system:
  • The landmark numbers are the powers of the base.
  • Starting from 1 (which is 70):
  • The first landmark number is 70 = 1.
  • The second landmark number is 71 = 7.
  • The third landmark number is 72 = 49.
  • The fourth landmark number is 73 = 343.
Thus, the 4th landmark number after 1 in a base-7 system is 343.
