Question

Which of the following does not represent the set of integers from 1 to 12?

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

{1, 2, 3, …, 10, 11, 12}

{1, 2, 3, 4, …}

{integers from 1 to 12}

Answer 1

{1, 2, 3, 4, …} is the only one that doesn't, since it doesn't end at 12, it'd be an infinite set.
