4. Find the union and intersection of these families, and prove your answers. (a) A = {A, ne N}, where A,, = {4n, 4n+ 1,..., 5n} for each natural number n. (b) A = {B: n = N), where B₁ = N. {n, n+1) for each natural number n. (c) A = {C₁; n = N}, where C = {1-n, n 4} for each natural - number n. (d) A = {D₂: ze Z}, where D₂ = {2z+6, 2z - 3} for all z € Z.
