Type how a set is written if the elements of the set are 5, 7, 9, 11?

Answer 1

It could be written as {5,7,9,11}, and also note that a set does not depend on the order in which you list its elements, so it could also be {9,7,5,11}, and any element can be listed an arbitrary number of times, e.g. it could be {9,5,5,5,11,7,11,9}.

Answer 2

Set A = {5, 7, 9, 11}

Answer 3

let the set D of numbers be D={5,7,9,11}

Answer 4

A=(5,7,9,11)

Answer 5

Is this what you mean?
A = {5,7,9,11}
