What type of set is A = {x : x ∈ ℤ, x is even}?
Answer and explanation
Correct answer: Infinite set
The set contains all even integers: ..., −6, −4, −2, 0, 2, 4, 6, .... There is always another even integer greater than any listed member, and the sequence also continues indefinitely in the negative direction. Therefore, the set has infinitely many elements and is an infinite set. Hence, option C is correct.
