Spotting arithmetic sequences

Arithmetic sequence 4, 7, 10, 13, 16 with equal +3 jumps, and paired first-last terms showing the arithmetic series formula

A sequence is an ordered list of numbers, where each number is called a term. In an arithmetic sequence, the gap between consecutive terms is always the same; this constant gap is called the common difference, ddd.

Step-by-step lessons covering Oxford AQA IGCSE Maths Sequences (Higher) for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 (Core: 1C and 2C; Extension: 1E and 2E) format. Since content from any part of the specification can appear on either paper, keep number and algebra fluency sharp throughout the course rather than leaving it until near the exam.
