Find common term for this sequence

In summary, the given sequence alternates between two values, and these can be found using the mod function or by raising a specific number to the power of the index. The two values are not 1 and 0, and the link for the mod function can be found in the previous response.

The Attempt at a Solution


I suspect this is not that hard, I get the denominators but the numerator alternates so I though I would need 6 to be the base of a power that alternates between 0 and 1 but I can't think of anything :/

Are you trying to find a formula for the nth term in the sequence?

You can handle the alternation between 1 and 6 by using the mod function, expressing things in mod 2.

Or, there's a special number that, when raised to the power of integer ##n##, gives alternating behavior of the type you seek. What number is that?

yes that's what I'm trying to do
I've never heard of a mod function:/ but i'll google it. A number that alternates between one and zero? can't think of one, hint?

The number doesn't alternate. Its powers do ('power' as in multiplying a number by itself an integer number of times). Every time we increase the power/index/exponent by 1, the result switches from one of the possible values to the other. Also, the two possible values are not 1 and 0.

The link for mod function is a hyperlink in my post above (blue text).
 

FAQ: Find common term for this sequence

1. What is the purpose of finding a common term for a sequence?

The purpose of finding a common term for a sequence is to simplify and represent a pattern or relationship between the terms in the sequence. This allows for easier understanding and manipulation of the sequence.

2. How do you find the common term for a sequence?

To find the common term for a sequence, you can use various methods such as identifying a mathematical formula, looking for a pattern in the terms, or using algebraic techniques.

3. Can there be more than one common term for a sequence?

Yes, there can be multiple common terms for a sequence. This can happen when there are multiple patterns or relationships present in the sequence.

4. What is the importance of finding a common term for a sequence in scientific research?

Finding a common term for a sequence is important in scientific research as it can help reveal underlying patterns and relationships between variables. This information can then be used to make predictions and inform further research.

5. Are there any limitations to finding a common term for a sequence?

Yes, there can be limitations to finding a common term for a sequence. Some sequences may not have a clear pattern or relationship, making it difficult to find a common term. Additionally, the common term may not accurately represent the entire sequence, as there may be outliers or other factors that affect the data.
