Numeric Patterns

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.

Types of Numeric Patterns

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.

Identifying Numeric Patterns

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)

Examples

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

Arithmetic Sequence

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.

Geometric Sequence

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.

Fibonacci Sequence

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.

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.
