Mark all thelemonis that are true (there might be more they one statement that is true) Let x bo a meal sequence and assume mat x x. Then A= (x_ :ne N) U (x ] is sequentialy compact. Let (x ] be a real sequence and A= (x, : BEN), where X E R. Define A, = (x : n2 k), & c N and lot #= (A, : ke /V). Than S is a covering of A. FA C A Is courtably infinite then A is not compact in (x ]te amo sequence and A= (x, :nc N) , where X C R. Demme A. = (x. : n2 k). ACN and let = [4 : AC /V). Then is a covering of A that has a finite subcovering. Las - 10. -1: WEN , men ) , 2 ia not empty
