## What is the formula for the sum of the first n terms of a geometric series?

The formula to find the sum of the first n terms of a geometric sequence is a times 1 minus r to the nth power over 1 minus r where n is the number of terms we want to find the sum for, a our beginning term of our sequence, and r our common ratio.

## What is a recursive formula?

In a recursive formula, each term is defined as a function of its preceding term(s). A recursive formula designates the starting term, a1, and the nth term of the sequence, an , as an expression containing the previous term (the term before it), an-1. The process of recursion can be thought of as climbing a ladder.

## What is the formula for geometric progression?

In mathematics, a geometric progression(sequence) (also inaccurately known as a geometric series) is a sequence of numbers such that the quotient of any two successive members of the sequence is a constant called the common ratio of the sequence. The geometric progression can be written as: ar0=a, ar1=ar, ar2, ar3,

## What is geometric mean?

In mathematics, the geometric mean is a mean or average, which indicates the central tendency or typical value of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum).

## How do you find the value of geometric series?

## What is the mean of Sigma?

Sigma is the 18th letter of the Greek alphabet and is equivalent to our letter ‘S’. In mathematics, the upper case sigma is used for the summation notation. The lower case sigma stands for standard deviation.
