Step 7 Objective
Generate terms of a sequence using term-to-term and position-to-term definitions of the sequence, on paper and using ICT.
- Examples of what pupils should
know and be able to do - Probing questions
- What if pupils find
this a barrier?
Probing questions
The term-to-term rule for a sequence is 'previous term + 2'. What does that tell you about the position-to-term rule? Do you have enough information to find the rule for the nth term? Why?
What do you look for in a sequence to help you to find the position-to-term (nth term) rule?
How would you go about finding the position-to-term (nth term) rule for this information on a sequence:
| Position | 3 | 5 | 10 |
|---|---|---|---|
| Term | 11 | 19 | 39 |
