The sum of the whole numbers 1 through 1,000 is 500,500.
It is instructive to note that you can rewrite 1+2+3+4....+99+100 as 1+100+2+99+3+98....+50+51 Then you can group each pair of numbers as (1+100)+(2+99)+(3+98)+...+(50+51) All of these couplets add up to 101, and there are 50 of them. Thus the sum of the first 100 whole numbers is 50x101. This can be calculated at 5,050.
The sum of all numbers between 1 and 5 is infinite.The sum of whole numbers between 1 and 5 is 2 + 3 + 4 = 9
The sum of whole numbers 1 through 30 is 465.
The sum of the composite numbers between 1 and 50 is 936.
The sum of the whole numbers from 1 to 100 inclusive is 5,050.

The sum of 9 odd numbers must be odd and so cannot be an number.
The nine odd numbers whose sum is 50 are 1, 3, 5, 7, 9, 11, 13, 15, and 1.
The sum is 150*151/2 = 11,325
