Which of the following is not an example of an infinite set?
Answer and explanation
Correct answer: Natural numbers less than 10
An infinite set has endlessly many distinct elements, whereas a finite set has a fixed number of elements. The odd natural numbers and the integers continue without end, and the positive multiples of 5 are also unlimited. Natural numbers less than 10 are only {1, 2, 3, 4, 5, 6, 7, 8, 9}, so this is a finite set. Therefore, option C is correct.
