The general term of Arithmetic progression (sequence)

작성자 Uploader : math1 작성일 Upload Date: 2016-03-15변경일 Update Date: 2016-03-15조회수 View : 490

In mathematics, an arithmetic progression (AP) or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 … is an arithmetic progression with common difference of 2.
If the initial term of an arithmetic progression is a_1 and the common difference of successive members is d, then the n-th term of the sequence (a_n) is given by:

a_n = a_1+(n-1)d, and in general a_n = a_m+(n-m)d.

a_n = a_m+(n-m)*d
