![]() ![]() The solution for this geometric sequence is explained below: a 8, d 3. Hence, the Solution of Arithmetic Sequence of 2,4,6,8,10,12,14,16 is 72.0. By using this Arithmetic Sequence Calculator, you can easily calculate the terms of an arithmetic sequence between two indices of this sequence in a few clicks. = k=1Σ 7 (2)+k × (2) = 8 / 2(2(2)+(8-1)(2)) To actually undertake the solution, he must be able to conceive a specific sequence of mathematical operations, that is, a program for working out the. X n = a + d(n−1) (We use "n−1" because d is not used in the 1st term)īy using the formula, we can find the summation of the terms of this arithmetic sequence. Arithmetic Sequences Calculator Instructions: This algebra calculator will allow you to compute elements of an arithmetic sequence. ![]() The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n n (a 1 + a n )/2 n 2a 1 + (n - 1)d/2. The general representation of arithmetic series is a, a + d, a + 2d.a + d(n−1)Īs per the rule or formula, we can write an Arithmetic Sequence as: If the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n a 1 + (n - 1)d. Also, look at the below solved example and learn how to find arithmetic sequences manually.įind the sum of the arithmetic sequence of 2,4,6,8,10,12,14,16?Ī is the first term and d is the common difference Learn from detailed step-by-step explanations Get walked through each step of the solution to know exactly what path gets you to the right answer. By using this formula, we can easily find the summation of arithmetic sequences.įor practical understanding of the concept, go with our Arithmetic Sequence Calculator and provide the input list of numbers and make your calculations easier at a faster pace.
