Geometric Sequence Suppose that a, b and c is a geometric sequence, and a>b>c, then a/b=b/c. a/b=b/c For example, 1, 7 and 49 is a geometric sequence. The next number can be obtained by multiplying its previous number by a particular number, that is, the common ratio of th...
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. ...
Two important types of sequences in mathematics are the arithmetic and geometric sequences. For those, recursive formulas allow us to determine a term knowing the previous one. It is also possible to find a generic term of those sequences using an explicit (that is, exact or definite) ...
