Formula for adding numbers 1 to n

WebIn the series 1 + 2 + 3 + 4 + ⋯, each term n is just a number. If the term n is promoted to a function n−s, where s is a complex variable, then one can ensure that only like terms are added. The resulting series may be manipulated in a more rigorous fashion, and the variable s can be set to −1 later. WebJan 18, 2024 · For our example n would be 10. The number of pairs would be this number divided by 2. You will notice that the size of the pair is the number of pairs plus 1. So, we could write use n to write (number of pairs) x (sum of each pair) = n/2 x (n +1) But remember, like before, we only want the sum of one row, not both. So we divide the …

Web$\begingroup$ @PaulHazen well depends on who is the user, computers do the first/2 and add last/2 in this order, calculators might use the "human" order, which would end up in a total different result. Either way, yes a/2 + b/2 is (a+b)/2 so your solution is more clear and its shorter and removed doubts. Thanks. $\endgroup$ – Miguel WebSolution: To find: The sum 46 + 47 + 48 + ... + 103.
