is an arithmeticsequence because each term is obtained by adding 4to the preceding number.In the arithmetic sequence50,45,40,…the common difference is 45-50=40-45=-5.General formulas for arithmetic sequencesinclude:the nth term a_n=a_1+(n-1)d,and the sum of the first n terms井鑫...

Arithmetic Sequence Suppose that a, b and c is an arithmetic sequence, and a>b>c, then a-b=b-c. They have a common difference, and let the common difference be x, then x=a-b=b-c. For example, 1, 2 and 3 is an arithmetic sequence, and their common difference is 2-1 as wel...

Arithmetic Geometric sequence is the fusion of an arithmetic sequence and a geometric sequence. In this article, we are going to discuss the arithmetic-geometric sequences and the relationship between them. Also, get the brief notes on the geometric mean and arithmetic mean with more examples. ...
