Once we find the value for \large {n}, we will substitute that into the arithmetic series formula together with the first and last terms to find the sum of the given arithmetic series. Finally, we have all the values that we need to calculate the sum of the given series which are \large {n=37} 37 \large {a_1} = 7 8 \large {a_n} = 187 187.

The sum of the arithmetic sequence formula is used to calculate the sum of all the terms present in an arithmetic sequence. We know that an arithmetic series of finite arithmetic sequencefollows the addition of the members that are of the form (a, a + d, a + 2d, …) where “a” = the first term and “d” = the common difference.
In an arithmetic sequence, every term after the first is obtained by adding a constant, referred to as the common difference (d). 1. Step 1: The nth term of an arithmetic sequence, an = a1 + (n – 1)d, where the first term is a1, the second term is a1 + d, the third term is a1 + 2d, etc and this gives the sum of series formula Sn = a1 + (a1 + d) + (...
Example 1:Find the sum of arithmetic sequence -4, -1, 2, 5, ... up to 10 terms. Solution: Here, a1= -4 and n = 10. Using the sum of arithmetic sequence formula, Sn=n2[2a1+(n−1)d]=102[2(−4)+(10−1)3]=5×(−8+27)=95Sn=n2[2a1+(n−1)d]=102[2(−4)+(10−1)3]=5×(−8+27)=95 ☛Also Check: Sum of Arithmetic Sequence Calculator Answer:Sum of arithmetic sequence -4, -...
This arithmetic sequence calculator (also called the arithmetic series calculator) is a handy tool for analyzing a sequence of numbers that is created by adding a constant value each time. You can use it to find any property of the sequence — the first term, common difference, nᵗʰ term, or the sum of the first n terms.
Definition 1: A mathematical sequence in which the difference between two consecutive terms is always a constant and it is abbreviated as AP. Definition 2: An arithmetic sequence or progression is defined as a sequence of numbers in which for every pair of consecutive terms, the second number is obtained by adding a fixed number to the first one.
- The general form of arithmetic progression is given by a, a + d, a + 2d, a + 3d, . . .. Hence, the formula to find the nth term is: a n = a + (n –...

Oct 6, 2024 · Categories: Mathematics. To find the sum of an arithmetic sequence, start by identifying the first and last number in the sequence. Then, add those numbers together and divide the sum by 2. Finally, multiply that number by the total number of terms in the sequence to find the sum. To see example problems, scroll down!

The sum of an arithmetic sequence is “the sum of the first n terms” of the sequence and it can found using one of the following formulas: Sn = n 2(2a + (n − 1)d) Sn = n 2(a1 + an) Here, a = a1 = the first term. d = the common difference. n = number of terms. an = nth term. Sn = the sum of the first n terms. 2.
