A geometric progression, also known as a geometric sequence, is a mathematical sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed number called the common ratio. For example, the sequence 2, 6, 18, 54, ... is a geometric progression with a common ratio of 3.
In mathematics, a geometric series is a series summing the terms of an infinite geometric sequence, in which the ratio of consecutive terms is constant.For example, the series + + + is a geometric series with common ratio , which converges to the sum of .
The nth element of an arithmetico-geometric sequence is the product of the nth element of an arithmetic sequence and the nth element of a geometric sequence. [1] An arithmetico-geometric series is a sum of terms that are the elements of an arithmetico-geometric sequence.
SageMath is designed partially as a free alternative to the general-purpose mathematics products Maple and MATLAB. It can be downloaded or used through a web site. SageMath comprises a variety of other free packages, with a common interface and language. SageMath is developed in Python.
The Pell numbers are defined by the recurrence relation: = {=; =; + In words, the sequence of Pell numbers starts with 0 and 1, and then each Pell number is the sum of twice the previous Pell number, plus the Pell number before that.
In historical works about Greek mathematics the preferred term used to be figured number. [ 3 ] [ 4 ] In a use going back to Jacob Bernoulli 's Ars Conjectandi , [ 1 ] the term figurate number is used for triangular numbers made up of successive integers , tetrahedral numbers made up of successive triangular numbers, etc.
where is the number of terms in the progression and is the common difference between terms. The formula is essentially the same as the formula for the standard deviation of a discrete uniform distribution , interpreting the arithmetic progression as a set of equally probable outcomes.
"The Nth Degree" (Star Trek: The Next Generation) "Nth Degree" (song) , a song by New York City band Morningwood A mathematically specious phrase intended to convey that something is raised to a very high exponent (as in "to the n th degree"), where n is assumed to be a relatively high number (even though by definition it is unspecified and may ...
