Numeric patterns are sequences of numbers that follow a specific rule or pattern. Understanding numeric patterns helps us predict future numbers in the sequence and can be useful in various mathematical and real-world situations.

**Arithmetic Sequences:**In arithmetic sequences, each term is obtained by adding a constant value to the previous term.**Geometric Sequences:**Geometric sequences have a common ratio between each pair of consecutive terms.**Fibonacci Sequence:**The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones.

To identify a numeric pattern, look for the relationship between consecutive terms. Ask yourself:

- Is there a consistent difference between each pair of consecutive terms? (for arithmetic sequences)
- Is there a consistent ratio between each pair of consecutive terms? (for geometric sequences)
- Is each term the sum of the two preceding terms? (for Fibonacci sequence)

Let's look at an example of each type of numeric pattern:

Find the next three terms in the sequence: 5, 8, 11, 14, ...

Answer: The common difference is 3. So, the next three terms are 17, 20, 23.

Find the next three terms in the sequence: 2, 6, 18, 54, ...

Answer: The common ratio is 3. So, the next three terms are 162, 486, 1458.

Find the next three terms in the Fibonacci sequence: 0, 1, 1, 2, 3, 5, ...

Answer: The next three terms are 8, 13, 21, since each term is the sum of the two preceding terms.

Here's a study guide to help you master numeric patterns:

- Understand the differences between arithmetic, geometric, and Fibonacci sequences.
- Practice identifying numeric patterns in given sequences.
- Work on solving for missing terms in numeric patterns.
- Explore real-world examples of numeric patterns, such as population growth or financial projections.
- Challenge yourself with more complex numeric pattern problems to enhance your problem-solving skills.

Represent and analyze patterns and functions, using words, tables, and graphs.

Use mathematical models to represent and understand quantitative relationships.

Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.

Analyze change in various contexts.

Identify and describe situations with constant or varying rates of change and compare them.

Connections to the Grade 4 Focal Points (NCTM)

Algebra: Students continue identifying, describing, and extending numeric patterns involving all operations and nonnumeric growing or repeating patterns. Through these experiences, they develop an understanding of the use of a rule to describe a sequence of numbers or objects.
