Lesson details
Key learning points
- Sequence notation becomes more formal in further studies.
- There is notation for a term, the next term and for general terms.
- You can use this notation to write the term-to-term rule.
Keywords
N^th term - The nth term of a sequence is the position of a term in a sequence where n stands for the term number.
Term-to-term - A term-to-term rule describes how to calculate the next term in the sequence from the previous term.
Fibonacci sequence - A Fibonacci sequence is a sequence where each term is the sum of the two previous terms.
Common misconception
Pupils may think that $$u_1$$ means that $$u$$ has a value of one.
$$u_1$$ refers to the first term in the sequence and $$u_2$$ refers to the second term. The subscript refers to the term number.
