![]() ![]() Use the formula S n n/2 a + a n to find the sum of sequence. Use the formula a n a + (n 1)d to find n. Step 1-> declare Function to find sum of seriesĬout<<"sum of series A. Find the sum of an arithmetic sequence with the first term, common difference and last term as 8, 7 and 50 respectively. Traverse the loop till n and keep adding the first term to a temporary variable with the difference.To use the first method, you must know the value of the first term a1 and the value of. ![]() Input the data as the first term(a), common difference(d) and the numbers of terms in a series(n) There are two ways to find the sum of a finite arithmetic sequence.What is an Arithmetic seriesĪrithmetic series is the sequence of numbers with common difference where the first term of a series is fixed which is ‘a’ and the common difference between them is ‘d’.Ī, a + d, a + 2d, a + 3d. Let’s look at a problem to illustrate this and develop a formula to find the sum of a finite arithmetic series. ![]() Given with ‘a’(first term), ‘d’(common difference) and ‘n’ (number of values in a string) and the task is to generate the series and thereby calculating their sum. As we discussed earlier in the unit a series is simply the sum of a sequence so an arithmetic series is a sum of an arithmetic sequence. In order to calculate the sum of the first terms, we use the formula of is equal to over two multiplied by two plus minus one. ![]()
