How to derive the nth term of a sequence from its partial sums
In short: If you possess the formula for the sum of the first n terms in a sequence, you can uncover the formula for the nth term itself. This video demonstrates that mathematical relationship.
It provides a method to determine the formula for the nth term of a sequence when the formula for its partial sums is already known.
