There is a formula to calculate this sum. It is, S = ½n(n + 1) In this question, n = 25 so the sum of the numbers from 1-25 is, ½ x 25 x 26 = 325
The sum of all numbers between 1 and n = n*(n+1)/2 The sum of all numbers between 1 and 999 = 999*1000/2 = 499500 The sum of all numbers between 1 and 9999 = 9999*10000/2 = 49995000 So, the sum of all numbers between 1000 and 9999 = 49495500
The sum of all prime numbers between 10 and 16 is 41.
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
Including 11 they are: 11+13+17+19 = 60

The sum of all prime numbers between 1 and 11 is 28.
The sum of all prime numbers between 60 and 75 is 272
The sum of all numbers between 1 and n = n*(n+1)/2 The sum of all numbers between 1 and 999 = 999*1000/2 = 499500 The sum of all numbers between 1 and 9999 = 9999*10000/2 = 49995000 So, the sum of all numbers between 1000 and 9999 = 49495500
The sum of all prime numbers between 10 and 16 is 41.
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
Including 11 they are: 11+13+17+19 = 60
The sum of all the odd numbers between 1 and 12000 is 36000000.
500
The sum of all even numbers between 0 and 398 (2-396) is 157,212. If you include 398 the sum is 158,802.
Including 61 and 97 the sum is 620
The sum of all prime between numbers 1 and 400 (2 through 399) is 13,887.
