Geometric Progression Formula:
From: | To: |
The geometric progression formula calculates the last term of a geometric sequence. A geometric progression is a sequence where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.
The calculator uses the geometric progression formula:
Where:
Explanation: The formula calculates the nth term of a geometric sequence by multiplying the first term by the common ratio raised to the power of (n-1).
Details: Geometric progressions are fundamental in mathematics and have applications in various fields including finance (compound interest), physics (exponential decay), computer science (algorithm analysis), and population growth models.
Tips: Enter the first term, common ratio, and total number of terms. All values must be valid numbers. The common ratio cannot be zero.
Q1: What is a geometric progression?
A: A geometric progression is a sequence of numbers where each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio.
Q2: Can the common ratio be negative?
A: Yes, the common ratio can be negative, which results in an alternating sequence where terms switch between positive and negative values.
Q3: What happens if the common ratio is 1?
A: If the common ratio is 1, all terms in the sequence will be equal to the first term, creating a constant sequence.
Q4: Can the common ratio be between 0 and 1?
A: Yes, if the common ratio is between 0 and 1, the sequence will decrease exponentially toward zero.
Q5: What are some real-world applications of geometric progressions?
A: Geometric progressions are used in compound interest calculations, radioactive decay, population growth models, computer algorithms, and many other exponential growth or decay scenarios.
