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.
The sum of the numbers 1 through 27 is 378.
The sum of the numbers from 1 through 100 is 5,050.
The sum of the whole numbers 1 through 1,000 is 500,500.
The sum of the first 250 integers is 31,125.

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
The sum of the first 250 prime numbers is 182,109.
The sum of the first 250 consecutive odd numbers is 250 squared or 62,500.
450+250=700
The sum of all odd numbers 1 through 99 is 9,801.
That's the number usually called the "average" of 150 and 250.It's 1/2 of the sum of the two numbers.1/2 (150 + 250) = 200.
