WebOct 6, 2024 · The formula for the sum of the first n terms of an arithmetic sequence is Sn = n(a1 + an) 2 How to: Given terms of an arithmetic series, find the sum of the first n terms Identify a1 and an. Determine n. Substitute values for a1, an, and n into the formula Sn = n(a1 + an) 2. Simplify to find Sn. Terms of an Arithmetic Series WebThe sum of the arithmetic sequence can be derived using the general arithmetic sequence, a n n = a 1 1 + (n – 1)d. Step 1: Find the first term. Step 2: Check for the number of terms. Step 3: Generalize the formula for the first term, that is a 1 and thus successive terms will be a 1 +d, a 1 +2d.
