Number Patterns

Humans have been fascinated by numbers for centuries, whether they are mathematicians or statisticians. They have so much potential, and we have yet to discover all the things we can do with them. As an example, the whole numbers represent all positive numbers, including zero, without any decimal or fractional parts. How about finding patterns in the whole numbers to find relationships? This is what makes numbers so fascinating or interesting. Detailed examples, charts, and explanations of Number Patterns in mathematics are presented in this article.

How do Number Patterns Work?

A Number Pattern refers to a sequence of numbers that follow a certain order in mathematics. Patterns typically describe the inverse relationship between numbers. The sequences of numbers can also be called patterns. It is first necessary to understand the rule being followed by the pattern in order to solve the problems involving the Number Pattern.

Types of Number Patterns

There are two common number sequence patterns:

1. Arithmetic Sequences

2. Geometric Sequences

The special sequences of Number Patterns are as follows:

1. Square Numbers

2. Cubic Sequence

3. Triangular Numbers

4. Fibonacci Numbers

Arithmetic Sequence

Arithmetic sequences are sequences of numbers with constant differences between consecutive terms in mathematics. Common differences between consecutive terms are called common differences.

Here are some examples of arithmetic numbers: 

1, 4, 7, 10, 13, 16, ...... is an arithmetic sequence because the difference between consecutive terms is 3.

1, 4, 8, 11, 15, 18, ...... is not an arithmetic sequence because the difference between consecutive terms is not a constant. 

Geometric Sequences

The geometric progression is a relation between two non-zero numbers in which, after the first term, each succeeding term is found by multiplying the previous term with a fixed, non-zero number.

Here are some examples:

4, 8, 16, 32, 64, ...... is a Geometric sequence because the step is multiplied by 2 which is the common ratio.

4, 8, 12, 16, 20, 24, ...... does not form a geometric sequence since the ratio between each step is different. 

Square Numbers

As a matter of mathematics, a square number is an integer that is the square of another integer. Sixteen is a square number that can be written as a square of the number four. Denoted by 42 or 4*4. 

Here are the square Number Patterns for the first 10 numbers:

1, 4, 9, 16, 25, 36, 49, 64, 81, 100.

A square Number Pattern is shown here where the first number is a square of 1, followed by a square of 2 which equals 4, a square of 3 equals 9, and so on until the square of 10 equals 100.

Cube Numbers

A cube number is one that has been multiplied three times by itself. The cube root of 27 is 3, which makes it a cube number. Denoted by 33 or 3 * 3 * 3.

Natural numbers have the following Cubic Sequence:

1, 8, 27, 64, 125, 216, 343, 512,

Triangular Numbers

Triangular numbers are used to count items arranged in equilateral triangles. When there are n points on a side of a triangular arrangement, the nth number of the formation equals the sum of the n natural numbers between 1 and n.

There are three triangles in the pattern of dots. The number sequence for the triangles is:

1, 3, 6, 10, 15, 21, 28, 36, …

Fibonacci Numbers

There is a sequence of numbers called Fibonacci Numbers in which each number equals the sum of the two preceding ones, starting with zero and one.

Following is the Fibonacci sequence:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ……..

The sum of 1 + 0 here is 1, so the third number in the sequence is 1. The sum of the 4th and 6th numbers (i.e., 2 + 3) is the 6th number, 5 (also the sum of the 4th and 6th numbers).
