[7.6] Substituting the formula for the first n natural numbers in 7.6, we get: [7.7] Which gives us: [7.8] Collecting like terms: [7.9] Factorising gives us the formula for the series of natural numbers from n 1 to n 2: Ken Ward's Mathematics Pages. Task. The program to calculate the sum of n natural numbers using the above formula is given as follows. 1 decade ago. So, you would calculate () =. We use while loop to iterate until the number becomes zero. To sum integers from 1 to N, start by defining the largest integer to be summed as N. Don't forget that integers are always whole and positive numbers, so N can't be a decimal, fraction, or negative number. The positive numbers 1, 2, 3... are known as natural numbers. Python code to print program name and arguments passed through command line. 200 xx (1+200)/2 = 20100 The sum of a finite arithmetic sequence is equal to the count of the number of terms multiplied by the average of the first and last terms.
