Sequences, series and spotting the pattern

Comparison diagram of arithmetic sequence 4, 7, 10, 13 with +3 arrows and geometric sequence 3, 6, 12, 24 with x2 arrows, with nth-term and sum formulas labelled A sequence is an ordered list of terms, while a series is what you get when you add those terms. The notation unu_nun​ means the nth term, and ∑\sum∑ means "add up".

Sequences and Series Lesson

  1. A Level
  2. /Maths
  3. /Sequences and Series

Step-by-step lessons on Edexcel A Level Maths Sequences and Series, covering 3.1 Arithmetic Sequences, 3.2 Arithmetic Series, 3.3 Geometric Sequences, 3.4 Geometric Series, 3.5 Sum to Infinity, 3.6 Sigma Notation, 3.7 Recurrence Relations, and 3.8 Modelling with Series. Each one builds up to exam-style questions. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
