Question

State whether the given set is finite or infinite.

{Multiple of $7$}

Answer 1

Infinite set:

We know that,

A set that contains countable number of different members or elements is called a finite set.

A set that contains unlimited number of different members or elements is called an infinite set.

Since the given set, {multiple of $7$} its counting will never come to an end.

Therefore, it is an infinite set.
