The sum of the integers from 1 to 100 inclusive is 5,050.
The sum of the first 1,000 integers (whole numbers) is 499,500.
The sum of the positive integers from 1,000 to 1,100 inclusive is: 106,050
The sum of the squares of the first 1000 positive odd integers (from 12 to 19992) is 1333333000.

The integers are 99, 100 and 101. There is also a set of consecutive even integers whose sum is 300. That set is 98, 100 and 102.
It is 2500.
The sum of all the digits of all the positive integers that are less than 100 is 4,950.
They are 2n+2
It is 100*(100+1)/2 = 50500.
you can say that 2/10 of every 10 integers is divisible by 5, so multiplying 2/10 by 100, giving you 200/1000 total integers are divisible by 5. half of all integers are odd, so divide 200/1000 by 2 is 100/1000, so you can correctly state that 100 odd integers under 1000 are divisible by 5.
