In this lesson, you will learn about the summation telescoping property and how to use it to find summations. The lesson walks through the process of finding the summation from k=1 to n of k to the cube and arrives at the conclusion that the sum is equal to T sub n squared, where T sub n is the nth triangular number. The lesson then introduces the telescoping property and applies it to finding the summation from k=1 to n of k. Finally, the lesson encourages students to practice using the telescoping property by trying to find the summation from k=1 to n of k squared.
