Activity: number patterns (terms) [lo 2.1, lo 2.3.1, lo 2.3.2]
9. did you know?
The numbers in a number sequence are also known as TERMS .
10. problem
Make your own number sequence!
With a friend, work through the following example:
- Draw a flow chart with two operator blocks:
- Fill the answers in on the right.
N- values
Your number sequence is 7 ; 12 ; 17 ; 22 ; 27
Your rule will be:
T n = (5 × n ) + 2
Term which
one = 5 n + 2
Thus: T 2 = (5 × 2) + 2 = 12
T 12 = (5 × 12) + 2 = 62
- If you are certain that you understand the above, compile your own number sequence.

Assessment
Learning Outcome 2: The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.
Assessment Standard 2.1: We know this when the learner investigates and extends numeric and geometric patterns looking for a relationship or rules, including patterns.
Assessment Standard 2.3: We know this when the learner represents and uses relationships between variables in order to determine input and/or output values in a variety of ways using;
2.3.1: verbal descriptions;
2.3.2: flow diagrams.
