18 <p>Two sets are shown in the diagram: an infinite set represents a set of whole numbers (which is the violet part), and the inner set (the pink part), which contains the<a>data</a>{3, 8, 13}, represents a finite set.

21 <p>Unlike a finite set, an infinite set can have continuity from both ends and has no end points. We have both the beginning and the ending elements in a finite set. An infinite set is one whose elements cannot be counted, while a finite set is one whose elements can be counted.</p>
