Number Sequences and Patterns

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 …

Leave a comment with the answers. Write the next three numbers and explain what the rule or pattern was.
