Integers are whole numbers without. We have already used Gauss's trick to sum the natural numbers. Sum to n of the Natural Numbers Using Differences. We can find the formula for a set of numbers using differences. For instance, the following table shows the sum of some natural numbers, but we have also used zero, for convenience: n. Sn. 01. 36. 10. 15. The sum of the coefficients. Cobol Program To Find Sum Of N Numbers In Arithmetic SeriesWe note the relationship: That is, the sum of n natural numbers is the sum of n+1 natural numbers less (n+1). Expanding the term for (k+1), we get: Which simplifies to: We. Cobol Program To Find Sum Of N Numbers FormulaSecond Try With Summation. Starting again, we note that the sum of the squares of the first n natural numbers is the sum of the first (n+1), less (n+1)2. Expanding the (k+1)th term: Expanding (n+1)2, and rounding up similar terms: Which gives us the sum of the first n natural numbers: The following graph is of y=x, and the rectangles represent the natural numbers 1, 2, 3, 4: The area of the triangular graph, if we take it as representing n numbers is: n. So the sum to n terms is, approximately: If we take En to be the error on the approximation to n terms: Looking at the graph, the error on each number is 1/2, so the error on the sum of the first n numbers, En, is n/2. So: Second Approach With Errors. As we cannot figure out the error this easily every time, we try another approach: . In the graph below, we have the first few natural numbers shown as rectangles on the graph y=x. The area under the graph approximates the sum of the natural numbers, so: . We note the difference between the sum of the first n natural numbers, and the sum to (n- 1) is n. The idea is that we look at the terms Sn- Sn- 2, et c, and write down the know differences, hoping that a pattern appears and we can write Sn- k, and then to write down the n- th term, from which we can extract a formula. And for the sum to (n- 2): Continuing to unravel: And one more: A pattern becomes clear. So we can write a general term, the k- th term: . According to number theory, we can represent numbers in one of these four ways: . After a short or. As I can't see any clear relationship, I make a table: n(n. Naturally, the minus signs alternate and the m values occur. Apart from this, I see nothing except.. Of course, I do another table: n. The length of the table indicates that I did not see anything quickly). However, the following relationship comes to mind: m=ceil(n/2) . Clearly. it is always bigger by n. The sum of the odd number is bigger. Application - Sum of Part of the Series of Natural Numbers. The sum of part of a series from n.
