Here is an example of a collapsing (telescoping) series
As you can see above, terms are shifted with some overlapping terms, which reminds us of a telescope. In order to find the sum, we will its partial sum
by cancelling ("collapsing") the overlapping terms,
Hence, the sume of the infinite series can be found by
