2. To be able to recognise and extend number sequences.
Lesson Objective
To be able to recognise and extend number sequences.

3. When a number follows a pattern, we call this a sequence.
For example:
2, 4, 6, 8, 10, 12, ….
What is happening to the numbers?

4. Each number is called a ‘term’ of the sequence.
2, , , , ….
1st Term
2nd Term
3rd Term
4th Term

5. We can generalise each sequence with a rule.
4, 7, 10, 13, ….
The start number is: 4
The rule is:
Add 3

6. What are the missing numbers in the following sequences.

7. If we know the rule and start number, we can write the sequence.
The term-to-term rule is:
Subtract 6
The start number is: 30
30, 24, 18, 12, ….

8. Write the first 4 terms of the sequence.
The start number is: 4
4, 10, 16, 22, ….
The term-to-term rule is:
Add 6 4
The start number is:
4, 8, 16, 32, ….
The term-to-term rule is:
Double it
The start number is: 2
2, 1, 0.5, 0.25, ….
The term-to-term rule is:
Half it 5
The start number is:
5, 0, -5, 10, ….
The term-to-term rule is:
Subtract 5
