Question

13. Let A (x:x=n-2, n <5). Find A when
(a) n = W. n E w
(b) n = N n E N
(c) n E l = 1​

Answer 1

Step-by-step explanation:

The given sets are:

A={x:x∈N} = {1,2,3,4.....}

B={x:x=2n,n∈N} = {2,4,6,8,10....}

C={x:x=2n−1,n∈N} = {1,3,5,7,9.......}

D={x:x is a prime number} = {2,3,5,7,11,13....}

∴ A∩B={1,2,3,4....}∩{2,4,6,8....}

= {2,4,6,8....}

= B

Hence

$A∩B=B</p><p>$
