Question 142893

the Roster form is the set builder form

This method is also known as {{{tabular}}} method. 

In this method, a set is represented by listing all the elements of the set, the elements being separated by commas and are enclosed within flower brackets { }. 

In your example:

{{{J}}} the set of natural numbers between {{{one}}} and {{{7}}}; it means in set {{{J}}} will be all numbers greater than {{{1}}} and less than {{{7}}}.

Solution:

J = {2,3,4,5,6} is the {{{Roster}}}{{{ form}}}.
