Exam points

  • Identify the constant addition or subtraction between consecutive terms and state the term-to-term rule, including decreasing sequences.
  • Use equal increments between known endpoint terms to fill missing positions in an arithmetic sequence.
  • Reverse a stated multiply-and-subtract rule to find an earlier term, undoing the operations in reverse order.
  • Continue related count sequences in a diagram table by applying the correct increment separately to each row.
  • Use a pattern shared by every term, such as an even count, to explain why a proposed value cannot occur.
