Question

4,7,10,....25 set builder form

Answer 1

As we all know that,there are two Methods of writing sets.

a.) Listing Method or roster Method

In this method we write all the elements of a set in curly brackets.

b.) Rule method or set builder form

In this method we do not write the list of all elements but we write the general elements using variable followed by a vertical line or colon and write the property of the variable.

So, let's take your example.

4,7,10.........25

Which we can write as ,

W = { 4,7,10......25 }

Hence

=). In set builder form

=) W = { x|x is a set of whole numbers and 3< 'x'<26 }

I hope this will helps you.

Thanks.
