A={1,3,5,7,...}B={0,2,4,6,8,...}

Answer 1

Indeed, An and B are sets of numbers with explicit patterns:A = {1, 3, 5, 7, ...} addresses the arrangement of all sure odd numbers. These numbers follow the example of beginning at 1 and afterward adding 2 repeatedly.B = {0, 2, 4, 6, 8, ...} addresses the arrangement of all non-negative even numbers. These numbers follow the example of beginning at 0 and afterward adding 2 repeatedly.So, A contains every one of the positive odd numbers, while B contains every one of the non-negative even numbers.
