Write the solution of this equality in set builder notation “G is the set of odd natural numbers that are less than 18" in roster form?”

The set G can be written in set-builder notation as {x | x is a natural number, x < 18, and x is odd}.

In roster form, this set can be written as:

G = {1, 3, 5, 7, 9, 11, 13, 15, 17}

where each element in the set satisfies the conditions stated in the set-builder notation.
