Multiplier a geometric progression

Writing functions:

geod(a, b)

A element comes after the b element.

The mathematical function known as the geometric progression multiplier plays an important role in the world of numbers and formulas. This function is used to determine the successive terms of a geometric progression and represents the ratio of each subsequent term to the previous one.

The geometric progression multiplier is indicated by the letter "q" and has a constant value for the entire sequence. It is calculated by dividing any subsequent term by the previous one:

q = a2/a1 = a3/a2 = a4/a3 = ...

Where "a1" is the first term of the sequence, "a2" is the second term, "a3" is the third term, and so on.

The exponential multiplier can be a positive or negative number. When the multiplier value is greater than one, the sequence is considered to be increasing, since each subsequent term exceeds the previous one. If the multiplier is between zero and one, then the sequence will be decreasing, since each subsequent term will be smaller than the previous one. If the multiplier value is negative, the sign of the sequence members will alternate.

The use of a geometric progression multiplier is common in various fields. In financial mathematics, it is used to model growth or decline over several time periods. This allows you to estimate the future value of assets or shares based on their current value and expected growth or decline.

The geometric progression multiplier is also used in physics in modeling exponential growth or attenuation processes. For example, it can be used to determine the intensity of the spread of an epidemic or the decay of radioactive material.

In education, the geometric progression multiplier helps students understand the pattern of growth or decrease of a numerical sequence. This allows them to better understand and apply the concept of exponent, which is the basis for further mathematical and scientific research.

In conclusion, the geometric progression multiplier is a mathematical function that is widely used in various fields. It allows you to define the subsequent terms of a geometric progression and be used to model the growth, decline, or change of things over time. This function plays an important role in mathematics, physics, finance, and education, helping researchers and students better understand and apply exponential concepts.
