hi in this video we're going to try to find a formula for this sequence so we have 1 0 1 0 and the three dots indicate that it goes on forever solution so let's start by looking at another sequence that might be familiar that alternates like this and that sequence is negative 1 to the n so this sequence is special because whenever the exponent is e...

Questions & Answers
Q: What is the goal of finding a formula for a sequence?
The goal is to find a mathematical expression that represents the sequence and can be used to generate any term of the sequence without explicitly listing them.
Q: How does the video manipulate the original sequence to obtain the desired one?
The video subtracts 1 from each term to change the ones to zeros. Then, it suggests dividing the sequence by 2, which converts the negative twos to ones.
Q: Why does the video compare the original sequence to (1)^n?
By analyzing the pattern of (1)^n, it becomes evident that even exponents result in 1 and odd exponents result in 1. This pattern helps in finding the formula for the given sequence.
Q: Can the suggested approach be applied to other sequences as well?
Yes, the approach shown in the video can be applied to other sequences where there is a pattern or relationship that can be identified and manipulated to obtain the desired sequence.
Summary & Key Takeaways

The video discusses finding a formula for a given sequence that alternates between 1 and 0 indefinitely.

By comparing it to the sequence (1)^n, where even exponents result in 1 and odd exponents result in 1, the video explores a pattern.

To transform the original sequence into the desired one, the video suggests subtracting 1 from each term and then dividing by 2.
