Question

= {1, 2, 3 ... 20). A = (multiples of 2}
B = (multiples of 4) and C = (multiples of 3),
list the elements of the following.
(a)A
(b)B
(c)C
(d)A`​

Answer 1

Step-by-step explanation:

A = {multiples of 2}

   In 1,2,3,4...20, multiples of 2 are 2, 4, 6, 8, 10, 12, 14, 16, 18,20.

Hence,

A = {2, 4, 6, 8, 10 ,12, 14, 16, 18, 20}

B = {multiples of 4}

   In 1,2,3,4,5....20, multiples of 4 are 4,8, 12, 16, 20

Hence,

B = {4, 8, 12, 16, 20}

C = {multiples of 3}

  In 1,2,3,4.....20, multiples of 3 are 3, 6, 9, 12, 15,18

Hence,

C = {3, 6, 9, 12 , 15, 18}
