the integers are a closed subset of the real numbers. In topological terms, it means that, for any real number that is not an integer, there is an “open set” around it.
Hope it helped pls mark as brainliest

plz dear describe it
A set of natural numbers are(1,2,3....)
Then the complement of the set is (-not defined,0)U(0,1)U(0,2)U....till infinity.
Any union of open set is open
So (-not defined,0)u(1,0)U(0,2)U....is open and (1,2,3........)is closed
thanks dear
Thanks a lot.....
