The terms of a geometric series form a geometric progression, meaning that the ratio of successive terms in the series is constant. This relationship allows for the representation of a geometric series using only two terms, r and a. The term r is the common ratio, and a is the first term of the series. As an example the geometric series given ... ### Geometric series - Wikipedia

A geometric series is the sum of the numbers in a geometric progression. For example: + + + = + × + × + ×. Letting a be the first term (here 2), n be the number of terms (here 4), and r be the constant that each term is multiplied by to get the next term (here 5), the sum is given by: (−) −In the example above, this gives: + + + = (−) − = − − = The formula works for any real ... ### Geometric progression - Wikipedia

The first is to calculate any random element in the sequence (which mathematicians like to call the "nth" element), and the second is to find the sum of the geometric sequence up to the nth element. When you sum the sequence by putting a plus sign between each pair of terms, you turn the sequence into a geometric series. ### How to Calculate the Sum of a Geometric Series | Sciencing

9/9/2018 · The sum of a convergent geometric series can be calculated with the formula a ⁄ 1-r, where “a” is the first term in the series and “r” is the number getting raised to a power. A geometric series converges if the r-value (i.e. the number getting raised to a power) is between -1 and 1.

Arithmetic Sequences and Sums Sequence. A Sequence is a set of things (usually numbers) that are in order. Each number in the sequence is called a term (or sometimes "element" or "member"), read Sequences and Series for more details. Arithmetic Sequence.

If in a sequence of terms each term is constant multiple of the preceding term, then the sequence is called a geometric progression.(G.P), whereas the constant multiplier is called the common ratio. In an A.P, the difference between \(n^th\) term and \((n-1)^th\) term will be a constant which is known as the common difference of the A.P.
