What type of set is E = {x : x is an even natural number}?
Answer and explanation
Correct answer: Infinite set
The even natural numbers are 2, 4, 6, 8, 10, and so on. For every even natural number, a larger even natural number can be found by adding 2. Therefore, the list never terminates and the set has infinitely many elements. Hence, E is an infinite set, not a finite or singleton set.
