Understanding Geometric Series
A geometrical series is a sequence of numbers where each term after the first is found by multiplying the late term by a fixed, non zero number ring the mutual ratio. The general form of a geometrical 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
Before dive into the Sum of Infinite Geometric series, it's indispensable to understand the sum of a finite geometrical series. The sum S n of the first n terms of a geometrical series can be calculated using the formula:
S n a (1 r n )/(1 - r)
This formula is infer from the properties of geometrical sequences and is crucial for understanding the demeanor of geometrical series.
The Sum of Infinite Geometric Series
The Sum of Infinite Geometric series is a special case where the number of terms is infinite. For an infinite geometric series to have a finite sum, the common ratio r must satisfy the condition r 1. If r 1, the series diverges, meaning it does not have a finite sum.
The formula for the sum S of an infinite geometric series is:
S a (1 r)
This formula is derived by take the limit of the sum of a finite geometric series as n approaches eternity. When r 1, the term r n approaches zero, simplifying the formula to the one advert above.
