Number patterns are sequences of numbers that follow a certain rule or relationship. These patterns can be found in various mathematical contexts, including arithmetic, geometric, and other types of sequences.

There are several types of number patterns, including:

- Arithmetic Patterns: These patterns involve adding or subtracting a constant number to each term to get the next term.
- Geometric Patterns: These patterns involve multiplying or dividing by a constant number to get the next term.
- Square Number Patterns: These patterns involve a sequence of numbers that are the result of multiplying a number by itself (e.g., 1, 4, 9, 16, 25...).
- Cubic Number Patterns: These patterns involve a sequence of numbers that are the result of raising a number to the power of 3 (e.g., 1, 8, 27, 64, 125...).

To find the rule of a number pattern, you can use the following steps:

- Look for the relationship between consecutive terms.
- Determine if the pattern is arithmetic, geometric, or another type of sequence.
- Write the rule as an equation or a set of instructions to generate the pattern.

Consider the following number pattern: 3, 6, 9, 12, 15...

This is an arithmetic pattern with a common difference of 3. The rule can be expressed as: *n _{th}* term = 3

Try solving the following problems to test your understanding of number patterns:

- Identify the type of pattern and find the rule for the sequence: 2, 4, 8, 16, 32...
- Determine the next three terms in the sequence: 5, 10, 20, 40, ...

Number Patterns

Number and Operations (NCTM)

Understand numbers, ways of representing numbers, relationships among numbers, and number systems.

Use factors, multiples, prime factorization, and relatively prime numbers to solve problems.

Algebra (NCTM)

Understand patterns, relations, and functions.

Represent, analyze, and generalize a variety of patterns with tables, graphs, words, and, when possible, symbolic rules.
