A geometric series is a sequence of numbers where each term is found by multiplying the previous term by a constant value called the common ratio. The general form of a geometric series is a + ar + ar^2 + ar^3 + ..., where a is the first term and r is the common ratio.
The sum of a finite geometric series can be found using the formula S = a(1-r^n)/(1-r), where S is the sum, a is the first term, r is the common ratio, and n is the number of terms. For an infinite geometric series, the sum can be found using the formula S = a/(1-r), as long as the absolute value of the common ratio is less than 1.
The common ratio in a geometric series is the number by which each term is multiplied to get the next term. It is usually represented by the variable r and is calculated by dividing any term by the previous term.
A series is geometric if each term is found by multiplying the previous term by the common ratio. You can also check for a constant ratio between consecutive terms to determine if a series is geometric.
Geometric series have many real-life applications, such as calculating compound interest in financial investments, modeling population growth, and in physics to describe the decay of radioactive materials. They are also commonly used in computer science, engineering, and statistics.
