Understanding Linear Sequences

This animation introduces linear (arithmetic) sequences by showing a set of numbers increasing or decreasing by a constant common difference. It visualizes terms as points on a number line and as a growing pattern of shapes, then builds the nth term formula an + b step by step. Designed for GCSE, IGCSE, and Edexcel O level students, it clarifies how to spot the common difference and use it to predict any term in the sequence.
