The sum of the first 50 counting numbers, excluding zero, is 1,251.
The sum of the first 50 whole numbers is 1,225.
the sum of first 50 consecutive odd numbers is 9801
sum of n natural number is n(n+1)/2 first 50 number sum is 50(50+1)/2 = 1275
To find the 9 odd numbers whose sum is 50 from 1 to 50, we can first calculate the sum of all odd numbers from 1 to 50, which is (50^2)/2 = 625. Next, we subtract the sum of the first 9 odd numbers (1+3+5+7+9+11+13+15+17 = 81) from the total sum, resulting in 625 - 81 = 544. Therefore, the 9 odd numbers whose sum is 50 from 1 to 50 are 19, 21, 23, 25, 27, 29, 31, 33, and 36.
Sum of 1st n even numbers: count*average = n * (2 + 2*n)/2 = n * (n+1) Sum = 50 * (2+100)/2 = 50*51 = 2550
The sum of the first 50 whole numbers is 1,225.
The sum of the first 50 even numbers is 2,550.
The sum of the first 50 odd numbers is 2,500.
The sum of the first 50 natural numbers is 1,251.
the sum of first 50 consecutive odd numbers is 9801
sum of n natural number is n(n+1)/2 first 50 number sum is 50(50+1)/2 = 1275

counting number between 50 and 75
The formula is: S_n = (n(n+1))/2 where S is the sum and n is the amount of numbers (starting at 1). So for 100: S_100 = (100(101))/2 = 50(101) = 5050 Alternatively, you could group 0+100 (0 isn't a counting number, just a placeholder), 1+99, 2+98, ..., 49+51, 50. You get 50 groups of 100 and 1 of 50. 50(100) + 50 = 5050. I think this is what Gauss did.
