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.
