Arithmetic sequences
Arithmetic sequences are also known as linear sequences because, if you plot the position on a horizontal axis and the term on the vertical axis, you get a
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 The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an=a1+d
