The sum of the first 500 counting numbers (1-500) is 125,001.
The sum of the first 500 odd counting numbers is 250,000.
The sum of the first 500 odd numbers is 250,000.
The sum of the first 5,000 odd numbers 25,000,000.
I think you asking what is 1 + 2 + .. 499 + 500. There is a simple way to compute such sums-- Find the average of the numbers and multiply by the number of items in the list. Further the average is just the sum of the first plus the last number in the list, since all of the numbers differs by the same amount. So, the average is (1+500)/2 and there are 500 number is the list, so the sum is (501/2)* 500 = 250*501. [I use * to mean multiply.}

The sum of the first 500 odd numbers is 250,000.
The sum of the first 5,000 odd numbers 25,000,000.
The sum of the first 500 even numbers, excluding zero, is 250,500.
The sum of the odd numbers (from 1) up to to 500 is 62500. The sum of an arithmetic series is given by: sum = 1/2 x number_in_series x (first + last) For the odd numbers from 1 to 500, there is: number_in_series = 250 first = 1 last = 499 which gives the sum as: sum = 1/2 x 250 x (1 + 499) = 62500.
1 + 3 + 5 + .... + 995 + 997 + 999 = 250000
The sum of the first 500 positive integers is: 125,250

The sum of the first thousand whole numbers can be calculated using the formula for the sum of an arithmetic series, which is n/2 * (first term + last term), where n is the number of terms. In this case, the first term is 1 and the last term is 1000. So, the sum would be 1000/2 * (1 + 1000) = 500 * 1001 = 500500.
1,000,000 * * * * * The 1st and 500th sum to (2*1-1)+(2*500-1) = 2*501 - 2 = 1000 The 2nd and 499th sum to (2*2-1)+(2*499-1) = 2*501 - 2 = 1000 There are 250 such sums So sum of all 500 odd numbers = 250*1000 = 250,000
