Skill: Extend growing number patterns

Explanation and Free Practice Resources

A growing number pattern is understood as a sequence in which each term is related to the previous term by a consistent rule, such as adding the same amount or multiplying by a familiar factor. Learners extend patterns of whole numbers by applying the rule to lists, tables, or number lines and explain how the quantities change; formal algebraic formulas, variable-based generalization, and complex or irregular sequences are beyond this scope.

Detailed Explanation: Extend growing number patterns

A growing number pattern changes by the same rule each time. To extend it, compare two neighboring numbers and find what was added or multiplied.

Example: Extend the pattern:

6, 11, 16, 21, □, □6,\ 11,\ 16,\ 21,\ \square,\ \square

Step 1: Compare neighboring numbers.

From 66 to 1111:

6+5=116+5=11

Check the next pair:

11+5=1611+5=16

The rule is add 55 each time.

Step 2: Find the next number.

Start with 2121 and add 55:

21+5=2621+5=26

Step 3: Find the number after that.

Add 55 again:

26+5=3126+5=31

So the completed pattern is:

6, 11, 16, 21, 26, 316,\ 11,\ 16,\ 21,\ 26,\ 31

The pattern grows by 55 each time.
