Infinite Geometric Series

What is an infinite geometric series?

Back

An infinite geometric series is the sum of the terms of a geometric sequence that continues indefinitely. It converges if the absolute value of the common ratio is less than 1.

What is the formula for the sum of an infinite geometric series?

Back

The sum S of an infinite geometric series can be calculated using the formula: S = a / (1 - r), where 'a' is the first term and 'r' is the common ratio.

What is the common ratio in a geometric series?

Back

The common ratio 'r' in a geometric series is the factor by which each term is multiplied to get the next term.

How do you determine if an infinite geometric series converges?

Back

An infinite geometric series converges if the absolute value of the common ratio |r| is less than 1.

What happens to the sum of an infinite geometric series if the common ratio is greater than or equal to 1?

Back

If the common ratio is greater than or equal to 1, the series diverges, meaning it does not have a finite sum.
