GCSE Secondary Maths Age 13-17 - Algebra: Sequences - Explained

The video tutorial explains how to identify and work with arithmetic sequences. It begins by introducing the concept of arithmetic sequences and how to recognize the pattern of adding a constant number. The tutorial then guides viewers through deriving the expression for the Nth term of the sequence. Finally, it demonstrates how to determine if a specific number is part of the sequence using the derived expression.
