Problem 4.2. Determine the intersection of each of the following indexed collections: (1) Let A = {An :n € N}, in which A, = {-n, n+ 1} for all n EN = {1, 2, 3, ...}. (2) Let B = {Bn :n ɛ N}, in which B, = [n – 2, n + 3] for all n e N. (3) Let C = {C, :n € N}, in which C, = [/2+, v13+ 1) for all n EN. (4) Let D = {D, :r € R}, in which D, = (-r² – 10, r² + 15] for all r E R. There is no need to justify the answers.
