Question: For each positive integer i, let S; be the following set: == S = {i,i+1,i+2,..., 2i + 1} That is, S; is the set

For each positive integer i, let S; be the following set: ==

For each positive integer i, let S; be the following set: == S = {i,i+1,i+2,..., 2i + 1} That is, S; is the set of integers between i and 2i + 1, inclusive. For example, S8 = {8, 9, 10,..., 17}. Also, let T = {1, 3, 5, 7,...}. Compute the following sets: 3 (a) US;= j=1 5 (b) Sk= k=3 5 () (s, T) = i=2 (d) Tn Si (US) i=2
