Sequences common mistakes

Common mistakes

• Generating sequence terms common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Generate terms of a sequence from a term-to-term rule or a position-to-term rule..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Generating sequence terms.

• Recognising sequences common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Recognise and use triangular, square and cube numbers and simple arithmetic progressions..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Recognising sequences.

• Recognising sequences common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Include Fibonacci-type and quadratic sequences where tier-appropriate..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Recognising sequences.

• Recognising sequences common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Include simple geometric progressions, other sequences and sequences involving surds where required..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Recognising sequences.

• Nth term common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Deduce expressions to calculate the nth term of linear sequences..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Nth term.

• Nth term common mistake 1

  Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Deduce expressions to calculate the nth term of quadratic sequences..

  Fix itShow the method first, then give the final answer in the required form. Apply this directly to Nth term.
