Numbers can have interesting patterns. Some of our problem solving strategies can help us figure out the rule of a number pattern or sequence.
There are many different types of number patterns. Just some of the common ones include:
Adding
Eg. 2, 4, 6, 8, 10…
Two is added on to each number.
Subtracting
Eg. 35, 30, 25, 20, 15, 10…
Five is subtracted from each number.
Multiplying
Eg. 2, 6, 18, 54, 162…
Each number is multiplied by three.
Mixed Pattern
Eg. 5, 8, 16, 19, 38, 41
In this pattern, three is added and then the number is multiplied by two. It continues + 3, x 2, + 3, x 2….
What is the rule for these number patterns? Can you leave a comment with the next three numbers in the sequence?
1. 2, 4, 8, 16, 32 …
2. 98, 90, 82, 74, 66 …
3. 181, 184, 187, 190, 193 …
4. 5, 6, 8, 11, 15, 20 …
5. 10, 12, 24, 26, 52, 54 …
