pattern

• Formulating an n term rule for a sequence without a common difference
Counting numbers are used, which are whole numbers excluding zero. The counting numbers are used to count the number of terms in the sequence. The n term rule is found by squaring the counting numbers
• A sequence is a set of numbers written in a special order by the application of a definite rule
• Increasing terms in a sequence
May involve addition or multiplication
• to find the nth term, we have to look for?

  a pattern, work backwards and guess and check strategies
• Finding the nth term in a sequence
1.Observing patterns in the sequence 2. Formulating a rule based on the pattern
• 3, 6, 9, 12, 15, _, _,?

  18, 21

  3 times table
• 3, 9, 15, 21, _, _?

  27, 33

  add 6 every term
