3. Patterns
sequences
and
We often need to spot a pattern in order to predict
what will happen next.
In maths, the correct name for a pattern of numbers
is called a SEQUENCE.
The first number in a SEQUENCE is sometimes
called the FIRST TERM; the second is the SECOND
TERM and so on.

4. Patterns and sequences
For any pattern it is important to try to spot what
is happening before you can predict the next
number.
The first 2 or 3 numbers is rarely enough to
show the full pattern - 4 or 5 numbers are best.

5. Patterns and sequences
For any pattern it is important to try to spot what
is happening before you can predict the next
number.
1, 2, ……
What’s the next number?

6. Patterns and sequences
For any pattern it is important to try to spot what
is happening before you can predict the next
number.
1, 2, 4,…
Who thought that the next number was 3?
What comes next?

7. Patterns and sequences
For any pattern it is important to try to spot what
is happening before you can predict the next
number.
1, 2, 4, 8, 16, …
What comes next?

8. Patterns and sequences
Look at what is happening from 1 TERM to the
next. See if that is what is happening for every
TERM.
5,
+3
8,
12,
17,
23,
…,
…

9. Patterns and sequences
Look at what is happening from 1 TERM to the
next. See if that is what is happening for every
TERM.
5,
+3
8,
12,
+3
X
17,
23,
…,
…

10. Patterns and sequences
Look at what is happening from 1 TERM to the
next. See if that is what is happening for every
TERM.
5,
+3
8,
12,
+4
17,

11. Patterns and sequences
Look at what is happening from 1 TERM to the
next. See if that is what is happening for every
TERM.
5,

12. Patterns and sequences
Look at what is happening from 1 TERM to the
next. See if that is what is happening for every
TERM.
5,
+3

13. Example;
find 8th term in the
given sequence
1, 4, 9, 16, 25, 36, ….

14. Patterns and sequences
Look at what is happening from 1 TERM to the
next. See if that is what is happening for every
TERM.

15. Patterns and sequences
Now try these patterns:
•3,

…
•128,
64,
32,
16,
