The amount of members of the geometric progression

Writing functions:

geosum(a, b, c)

Where:

a - the first member of progression, b - member progression when the last member, c - multiplier progression.

A geometric progression is a sequence of numbers in which each subsequent number is obtained by multiplying the previous one by a constant number called the denominator. Mathematically, a geometric progression is represented by the formula An = A1 * r^(n-1), where An is the nth term of the progression, A1 is the first term of the progression, r is the denominator of the progression, n is the number of the term.

The sum of the terms of a geometric progression is an important concept in mathematics. It is calculated using the formula Sn = A1 * (1 - r^n) / (1 - r), where Sn is the sum of n terms of the progression.

The use of geometric progression and its sum is widespread in various fields. In the financial sector, geometric progression is used to calculate future investment values and interest rates. It also finds applications in geometry, physics, statistics and economics.

Knowledge of the mathematical function of the sum of the terms of the geometric progression allows you to accurately calculate various parameters in problems related to changes in quantities over time or in space. This allows you to predict future values and draw conclusions based on data obtained from a geometric progression.

Using the sum of the terms of the geometric progression also facilitates data analysis and allows you to find patterns in sequences of numbers. This is important for determining trends and predicting the behavior of quantities in the future.

In conclusion, the mathematical function of the sum of the terms of a geometric progression has wide application and use in various fields of knowledge. Understanding it allows you to accurately calculate values, make predictions, and analyze data.
