GCSE Maths Algebra Playlist | Sequences | Lesson 7 of 9

Sequences are ordered lists of numbers (called "terms"), like 2,5,8. Some sequences follow a specific pattern that can be used to extend them indefinitely. For example, 2,5,8 follows the pattern "add 3," and now we can continue the sequence. Sequences can have formulas that tell us how to find any term in the sequence.

An algebraic sequence, also known as an arithmetic sequence, is a type of sequence in which the difference between every consecutive term is the same.

Key learning outcomes for this video:

2. To be able to calculate the nth term of an arithmetic sequence.
3. To be able to calculate the nth term of a quadratic sequence.
4. To be able to check if a given value is a term of a sequence.
