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 Edexcel IGCSE Maths Sequences (Higher) for IGCSE Maths. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Build confidence with the shared Foundation-tier content first, since roughly 40% of Higher-tier marks are targeted at the grades 4–5 boundary that both tiers have in common.
