Formalising a sequence

Sequences

Unit Summary

In this unit we develop knowledge of sequences to be able to identify, determine, and continue arithmetic sequences. We finish the unit by looking at how sequences may be reprsented graphically.

Lesson Summary

You will learn to appreciate that a sequence is a succession of terms usually formed according to a rule.

Key Notes

  • A pattern of objects can be made by following a rule.
  • These rules can be described in words.
  • The number of objects each time is the term.
  • Missing terms in the sequence can be found using the rule.

Vocabulary To Learn

  • Term: Each value or pattern in a sequence is called a term.

Common Mistakes To Avoid

  • Pupils can mix up describing how patterns grow or the relationships between objects in the pattern.

3 Quick Questions (With Answers)

1. Solve this in steps: explain the method from this lesson and why each step matters.

Each value or pattern in a sequence is called a term. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Pupils can mix up describing how patterns grow or the relationships between objects in the pattern. Correction: Pupils should verbalise their description, using the keyword 'term' , making it clear which way they are describing their pattern.
