51st
Following the fiftieth
Fifty-first in a sequence.
The 51st state is a common reference to territories or regions that might become the next U.S. state, or jokingly to countries seen as overly aligned with American interests: Puerto Rico could become the 51st state.
Area 51, the secretive Nevada military base, takes its name from a map grid designation.
