Question

State which of the following sets are finite and which are infinite.

$\left\{Multiplesof7\right\}$

Answer 1

A set that contains countable number of different members is called a finite set and a set which contains unlimited or uncountable number of different members is called an infinite set.

Given set:

$\left\{Multiplesof7\right\}$

Multiples of 7 are $\left\{7,14,21,28,..............\right\}$

The given set contains uncountable number of member.

Hence, the set $\left\{Multiplesof7\right\}$ is Infinite set.
