An arithmetic sequence is a sequence where each term increases by addingsubtracting some

Arithmetic sequences The simplest sequence is the sequence (0, 1, defined by g n for every n e N In general, an arithmetic sequence is specified by In the next example the common difference is negative E X A M P L E 2 An arithmetic sequence of decreasing terms Write a formula for the nth term of the

livescore volleyball 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 Key Concepts A recursive formula for an arithmetic sequence with common difference d d is given by an=an−1+d,n≥2 a n = a n − 1 + d , n ≥ 2 An explicit
