The set includes all natural numbers greater than or equal to 53. Adding any two numbers from this set will result in another number greater than or equal to 53, thus the set is closed under addition.

Decide Whether or Not the Set Is Closed Under Addition {n∈N:n≥53}\{ \mathrm { n } \in \mathrm { N } : \mathrm { n } \geq 53 \}{n∈N:n≥53}
