Learn about the summation telescoping property and how it can be used to find summations.

- What is the summation telescoping property?
- How can you use the summation telescoping property to find sums?
- What is the formula for the sum of k^3 from k = 1 to n?
- How is the summation of k^3 related to triangular numbers?
- How can you find the summation from k = 1 to n of k using the summation telescoping property?

This lesson is an incredibly important and useful property of summations. The summation telescoping property is an alternate way of finding summations of sequences. This property can be used for some summations that we already know, and for others that we have not yet found. This is a must-see lesson for finding sequence sums.
