Question

For every n whole numbers,what is the range?

Answer 1

The set of whole numbers begins from 0 and stretches till infinity.
Thus range of first n whole numbers would always be [0,(n-1)] , i.e. zero to n-1.
This is because the first whole number is zero and the last, consequently, will always be n-1 if we are taking n numbers into account.

For example, the range of first 20 whole numbers will be [0,19].
