Create a pattern with the rule n - 4
Natalka [10]

The pattern of rule n-4 can consist of several numbers depending on the value of n (integer, whole number, natural number or prime number)

<h3>Further explanation </h3>

Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.

The main composition of algebraic expressions are:

• 1. phrases

algebraic forms separated by arithmetic operations

consists of one phrase (monomial) to many phrases (polynomial)

• 2. variable

is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.

• 3. constants

is a fixed value, can be a number

• 4. arithmetic operations

operations {\displaystyle \boxed {+}, \boxed {-}, \boxed {:}, \boxed {x}}

Numbers in mathematics can be divided into several terms

  • 1. integer

numbers consist of positive, negative and 0 numbers

  • 2. natural numbers

numbers consisting of positive numbers, starting with number 1

  • 3. whole number

a number consists of positive numbers and zeros

  • 4. prime number

numbers that can only be divided by numbers themselves and the number 1

And examples of other numbers such as imaginary numbers, real numbers, rational numbers, etc.

Integers themselves consist of

  • 1. positive integers

the number to the right of the number 0 is 1,2,3 ...

  • 2. negative integers

the numbers to the left of the zeros are -1, -2, -3 ...

  • 3. number 0

n-4 is an algebraic form

the pattern is generated from rule = (n-4)

There are several possible values ​​of n that can be entered to form a pattern

  • if it's an integer, the value of n = let's say -3, -2, -1,0,1,2,3

pattern = -7, -6, -5, -4, -3, -2, -1, ...

  • if it's a natural number then the value of n = let's say 1,2,3

pattern = -3, -2, -1, ...

  • if it's a whole number then the value of n = let's say 0,1,2,3

pattern = -4, -3, -2, -1, ...

  • if it's prime number then the value of n = let's say 2,3,5,7 ...

pattern = -2, -1,1,3, ....
