set of all even natural numbers less than 10 = {2, 4, 6, 8}
Yes, there are infinitely many natural numbers greater than 9. Natural numbers start from 1 and continue indefinitely, so numbers like 10, 11, 12, and so on, all qualify as natural numbers greater than 9. The set of natural numbers is unbounded, meaning there is no largest natural number.
There are 1000 - 9 = 991 of them.
The mean of a set of numbers is defined to be the quotient of the sum of all the numbers divided by how many numbers are summed. In this instance, (13 + 2 + 15 + 10 + 5)/5 = 9.
The sum of the first 10 natural numbers is 51, with an average of 5.1
