This animation introduces linear (arithmetic) sequences, showing how each term increases or decreases by a constant common difference. It visually builds a number pattern, identifies the first term and common difference, then derives and applies the formula nth term = a + d(n-1). A worked example demonstrates finding a specific term, making it ideal for GCSE, IGCSE, and Edexcel students learning sequence formulas.

In last slide remove the formula and add new formula: nth term=a+d(n-1). a=first term, d=Common difference, n=term number. Give one example and use formula to find nth term
