An infinite set is a set whose elements can not be counted. An infinite set is one that has no last element. An infinite set is a set that can be placed into a one-to-one correspondence with a proper subset of itself.

Which of the following set is an infinite set?

The set of all integers, {..., -1, 0, 1, 2, ...} is a countably infinite set. The set of all even integers is also a countably infinite set, even if it is a proper subset of the integers. The set of all rational numbers is a countably infinite set as there is a bijection to the set of integers.

What is infinite set example?

Examples of infinite set:

1. Set of all points in a plane is an infinite set. 2. Set of all points in a line segment is an infinite set.
