Do Telescoping Series Always Converge. convergence of a telescoping series. determine whether ∑ n = 1 ∞ 1 n ( n + 1) is convergent and if so find the sum. I have used the telescoping series test and found. A telescoping series is a series where each term u_k uk can be written as u_k = t_ {k} – t_ {k+1} uk = tk −tk+1 for some series t_ {k} tk. This is a challenging sub-section of algebra.
Telescoping series are a type of mathematical series in which the terms are related in such a way that each successive term can be expressed as a fraction of the preceding term. The aim of a telescoping series is to reduce the number of terms from an infinite sum to a finite sum, making it easier to calculate the total sum. But the question is, do telescoping series always converge to a finite sum?

The answer is yes, telescoping series always converge to a finite sum, but the process requires a little bit of work. To find the sum of a telescoping series, you first need to find the common ratio between the terms. Once you have the common ratio, you can then apply the formula for the sum of a geometric series and calculate the total sum.
The formula for the sum of a geometric series is as follows:
- S = a + ar + ar² + ar³ + ar⁴ + … + ar^n
- where: a = first term, r = common ratio, and n = number of terms.
To illustrate how the formula works, let’s consider the following telescoping series:
- 1 + 1/2 + 1/4 + 1/8 + 1/16 + … + 1/2^n
In this series, the common ratio is 1/2, so the sum of the series can be calculated by plugging the values into the formula:
- S = 1 + (1/2) + (1/2)² + (1/2)³ + (1/2)^4 + … + (1/2)^n
- S = 1 + 1/2 + 1/4 + 1/8 + 1/16 + … + 1/2^n
- S = 2 – 1/2^n
From this, we can see that the sum of this telescoping series is 2, which is a finite number. This proves that telescoping series always converge to a finite sum.
