Why use mathematical induction to get the sum of a sequence? Also, if there are any websites you can recommend that will be a help too. However, I need an explanation rather than examples. Thank you for any helpful replies.

REVISED QUESTION: Why use mathematical induction to prove the sum of a sequence is valid?

Mathematical induction is a very powerful tool for creating proofs. Because the technique can be a little mystifying when first presented, it helps to have a clear example to illustrate it.
