{ }

{1, 2, 2, 3, 4, 4, 5, 6, 6, 7, 8, 8, 9, 10, 10, 12, 14}

{2, 4, 6, 8, 10}

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14}

Answer 1

I don't get what your question actually is, but...
{1, 2, 2, 3, 4, 4, 5, 6, 6, 7, 8, 8, 9, 10, 10, 12, 14} --> i dunno xD
{2, 4, 6, 8, 10}-->A and B
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14}-->A or B

Answer 2

could you describe the symbol between A and B? Is it the union, intersection, what?

Answer 3

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 14} ?

Answer 4

No, I meant in the original problem, there's undoubtedly some symbol between A and B in "what is A B?"

What does it look like?
