Question

the set of the even integers between 11 and 21

Answer 1

Given:

Integers between 11 and 21

To find:

The set of even integers

Solution:

The required set is {12, 14, 16, 18, 20}.

We can obtain the set by taking out the integers that are divisible by two.

The total integers between 11 and 21 are as follows-

12, 13, 14, 15, 16, 17, 18, 19, 20

Out of these, the even integers are the ones divisible by 2.

So, the required integers are 12, 14, 16, 18, and 20.

The set={12, 16, 14, 18, 20}

Therefore, the required set is {12, 14, 16, 18, 20}.
