You can use patterns
to decide what numbers come next in a series of numbers.
Look for a number
pattern.

What is the
difference between each number?

Each number is 3
more than the one before it.

Use the
number
pattern to find the next three numbers.
11+3=14 14+3=17
17+3=20

2, 5, 8, 11, 14,
17,
20


What's the
difference between the number.

Each number is
2
less than the number before.

Use the
number
pattern to find the next three numbers.
11, 9, 7,__, __, __, 
112=9 92=7 72=5
52=3 32=1

11, 9, 7, 5, 3,
1 
You can use number
patterns to complete a table.
The number
pattern is the rule
for the table.
You always look for the pattern from the
INPUT to the OUTPUT.
INPUT 
2 
3 
4 
5 
9 
10 
OUTPUT 
5 
6 
7 



What's the Rule?____________________
What do you have to do to each INPUT
number to get the OUTPUT
number below it?

You add
3 to each INPUT
number to get the OUTPUT
number.

The
rule for this table is
Add 3.

Use the rule to
complete the table. Then write the rule.
INPUT 
2 
3 
4 
5 
9 
10 
OUTPUT 
5 
6 
7 
8 
12 
13 
Rule: Add 3
Find the number
pattern to complete the table.
Then write the rule.
INPUT 
11 
10 
9

OUTPUT 
7 
6 
5 



Rule
: ________________
