Answer:
{1, 2, 3, 4, 5}
Step-by-step explanation:
Since the set builder condition says {x | x ∈ ℕ and x < 6}, that is, x is an element of natural numbers and x is less than 6. So, we list the natural numbers less than 6 starting from the first natural number, 1.
So {x | x ∈ ℕ and x < 6} = {1, 2, 3, 4, 5}
