Answer 1

Answer:

Answer 2

Answer:

A = {2, 4, 6, 8, 10,.....}

Step-by-step explanation:

We know that,

A = {x : x = 2n, where n ∈ N}

Let it be of the Set A.

Now,

x = 2n

and since n ∈ N

n = 1, 2, 3,.......

Thus,

x = 2, 4, 6, 8, 10,........

Hence,

A = {2, 4, 6, 8, 10,......}

Is the required set.
