Arithmetic sequence formula for the nth term. Use the Number Sequence Calculator to identify patterns in arithmetic, geometric, and Fibonacci sequences. You can also solve for the common difference from two known terms. Math Arithmetic Sequence Calculator Arithmetic Sequence Calculator Enter your sequence's first term (a₁), common difference (d), and term index (n) to find the nth term and the sum of the first n terms of any arithmetic sequence. The nth term is a formula used to generate any term of a sequence. In cases that have more complex patterns, indexing is usually the preferred notation. Substitute the first term a1 = 36 and common difference d = 8 into the formula. To find a given term, substitute the corresponding value of n into the nth term formula. Jul 23, 2025 · The arithmetic sequence formula is a way to describe the n-th term of an arithmetic sequence. Indexing involves writing a general formula that allows the determination of the nth term of a sequence as a function of n. If we know the first term of the sequence (denoted by 'a') and the common difference ('d'), we can determine any term in the sequence using this formula. ackcjx sytqf vlkpr pmtjyi mqlmyw gqwkzt fjjv fhh whzjk xajof
