                ### Instruction: help me answer this question Write the following sets in the set-builder form.
(i) (3, 6, 9, 12)
(ii) {2, 4, 8, 16, 32}
(iii) {5, 25, 125, 625}
(iv) {2, 4, 6 … }
(v) {1, 4, 9 … 100}, think step by step
                ### Assistant: In each case, I have described the sets using the set-builder notation, where x is the element of the set defined by a rule or condition. , The answer is (i) {x: x = 3n, n ∈ N and 1 ≤ n ≤ 4}
(ii) {x: x = 2n, n ∈ N and 1 ≤ n ≤ 5}
(iii) {x: x = 5n, n ∈ N and 1 ≤ n ≤ 4}
(iv) {x: x is an even natural number}
(v) {x: x = n^2, n ∈ N and 1 ≤ n ≤ 10}
