Derive arithmetic series formula
WebAug 16, 2024 · The derivation of the formula as explained in many textbooks and online sites is as follows. To find the sum of an arithmetic sequence for the first n terms S n, we can write out the sum in relation to the first term a 1 and the common difference d. S n = a 1 + ( a 1 + d) + ( a 1 + 2 d) + ( a 1 + 3 d) +... + a n WebTo derive the above formula, begin by expressing the arithmetic series in two different ways: Rewriting the terms in reverse order: Adding the corresponding terms of both sides …

WebWe can write the finite arithmetic sequence as. Clearly, the first term is 1 1, the last term is 100 100, and the number of terms being added is also 100 100. Substitute the values into the formula then simplify to get the sum. … WebThe general formula for determining the sum of an arithmetic series is given by: S n = n 2 [ 2 a + ( n − 1) d] or S n = n 2 ( a + l) For example, we can calculate the sum S 20 for the arithmetic sequence T n = 3 + 7 ( n − 1) by summing all the individual terms:
