Video: Arithmetic Sequence

arithmetic sequence  Learn how to write an arithmetic sequence in general terms, using a common difference d and a An arithmetic sequence can also be defined recursively by the formulas a1 = c, an+1 = an + d, in which d is again the common difference between consecutive

This algebra video discusses the math formulas used when dealing with arithmetic sequences Algebraic Definition of Arithmetic Sequences for all positive integers n n where d d is a constant called the common difference So, the middle term is the

A sequence such as 1, 5, 9, 13, 17 or 12, 7, 2, –3, –8, –13, –18 which has a constant difference between terms The first term is a1, the common difference is d Explicit formula · Given the first term and the common difference of an arithmetic sequence, we can find the nth term of the sequence an by using the explicit
