# The range of first n whole numbers is?

Solution: We know that n, whole  numbers

0 ,1 , 2 ,3,  ......................... n

So consider a example  : range of first 2 whole number

⇒ 0 , 1 are first two whole numbers . So n doesn't get included in first n whole numbers.

⇒ So first n  whole numbers are 0 , 1, 2 , 3 , ................ n-1

⇒ we know that Range = Highest observation - Lower observation

⇒ (n-1 ) - 0 = n-1

The Range of first n whole numbers is ( n -1 )
