Question

If A={x :x =4n+1,n<=5,n€N} and B={x :x =3n,n<=8,n€N },Find A triangle B.​

Answer 1

Answer:

{3,5,6,12,13,15,18,17,24}

first we will write both set A and set B in roster form

A={5,9,13,17,21}

B={3,6,9,12,15,18,21,24}

now A union B={3,5,6,9,12,13,15,18,17,21,24}

A intersection B={9,12}

and the final answer is above.
