Math Problem Statement
2 + 4 + 8 + 16 +32+... what is the sum of the geometric series
Solution
The given series is a geometric series:
In a geometric series, each term is multiplied by a constant ratio to get the next term. Here, the first term and the common ratio .
If the series is infinite, the sum of an infinite geometric series is given by the formula: However, since , which is greater than 1, the series does not converge to a finite sum. Therefore, the sum of this infinite geometric series does not exist.
If the series is finite (e.g., stopping after a certain number of terms), the sum of the first terms of a geometric series is: For your series, with and , the sum of the first terms is:
Do you want to calculate the sum for a specific number of terms, or further details on how this works?
