Arithmetic Sequence Formula: Definition, Formula, Examples

arithmetic sequence  How do I find the nth term of an arithmetic sequence? · Multiply the common difference d by · Add this product to the first term a₁  This algebra video discusses the math formulas used when dealing with arithmetic sequences

Solution The difference is constant, -4 Hence, it is a common difference of the sequence Note that this common difference is negative, hence we can say What is an arithmetic sequence? For many of the examples above, the pattern involves adding or subtracting a number to each term to get the next term Sequences

Solved Examples for Arithmetic Sequence Formula · a_n =a + d · a_n = 0 + times 2 · a_n = 28 · S = frac{n}{ 2 }  If you're given the first few terms of an arithmetic sequence, you just need to identify the first term and the common difference (the number being added each
