Relation between AM and GM, Arithmetic-Geometric series
An arithmetic-geometric series is a sequence of numbers in which the ratio between any two consecutive numbers is constant, while the difference between consecutive numbers is not constant. This constant ratio results in a consistent pattern of ratios, which eventually converge to a single value called the geometric mean (GM). Similarly, the difference between consecutive numbers in the geometric series also converges to the arithmetic mean (AM).
Geometric series: A sequence of numbers in which the ratio between any two consecutive numbers is constant.
Arithmetic series: A sequence of numbers in which the difference between consecutive numbers is constant.
The geometric mean (GM) of a series of numbers is the average of the numbers in the series, and the arithmetic mean (AM) is the average of the differences between consecutive numbers.
In other words, the GM is the average of the numbers in the series, and the AM is the average of the differences between consecutive numbers.
Examples:
The sequence 1, 3, 9, 27 follows the geometric series with a common ratio of 3.
The sequence 1, 3, 5, 7 follows the arithmetic series with a difference of 2 between consecutive numbers.
The geometric mean of the series 1, 4, 16 is 8, and the arithmetic mean is 4
