May 22, 2018 · To get the result in O(1) time we can use the formula of summation of n natural numbers.For the above example, a = 4 and N = 23, number of multiples of a, m = N/a(integer division). The multiples are 4, 8, 12, 16, 20.
Hence, required sum of the integers between 100 and 200 that are divisible by 9 is 1683. (ii) The sum of the integers between 100 and 200 which is not divisible by 9 = (sum of total numbers between 100 and 200) – (sum of total numbers between 100 and 200 which is divisible by 9). Hence, the required sum is 13167. Question 6:

The sum of these composite numbers, including 100, is 3989.The sum of all numbers between 1 and 100 is 5,050. From this we need to subtract the sum of 1 plus all the prime numbers below 100.
This is a simple division series; each number is one-half of the previous number. In other terms to say, the number is divided by 2 successively to get the next result. 4/2 = 2 2/2 = 1 1/2 = 1/2 (1/2)/2 = 1/4 (1/4)/2 = 1/8 and so on.

Find the sum of the consecutive numbers 1-100: (100 / 2)(1 + 100) 50(101) = 5,050 . More Examples. Take a look at this diagram to help you visually understand what the formula is saying.

C Program to Find Sum of N Natural Numbers. As we all knows that positive numbers from 1, 2, 3, ... are natural numbers. Therefore here we only have to ask from user, the value of n, that is upto how many term, the natural number continues, and find sum of that natural number.
