Is the set of even counting number?

The set of even counting numbers includes all positive integers that are divisible by 2, such as 2, 4, 6, 8, and so on. This set is infinite and can be expressed mathematically as {2n | n ∈ ℕ}, where ℕ represents the set of natural numbers. Therefore, the set of even counting numbers is a well-defined subset of the natural numbers.
