i just need help..lolzz...in fact don't really know where to start..y the way i know the equation
A geometric progression is a sequence of numbers where each term is obtained by multiplying the previous term by a constant value called the common ratio. For example, in the sequence 2, 6, 18, 54, the common ratio is 3.
The common ratio in a geometric progression can be found by dividing any term by the previous term. This will give you the same value for all terms in the sequence.
The formula for finding the nth term in a geometric progression is an = a1 * r^(n-1), where an is the nth term, a1 is the first term, and r is the common ratio.
The sum of a finite geometric progression can be found using the formula Sn = a1 * (1-r^n)/(1-r), where Sn is the sum of the first n terms, a1 is the first term, and r is the common ratio.
Geometric progression is used in various fields such as finance, engineering, and science. It can be used to model population growth, interest rates, and the decay of radioactive substances. It is also used in creating computer algorithms and in analyzing data in statistics.
