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
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, ....

The necessary formulas to get the area of a circle’s segment are the area of the circle’s sector and the triangle it is bounded by.
Hence the formula for the segment’s area is:Area of Segment = Area of sector – area of the triangle.
The formula of the area of a circle’s sector is:Area of Sector =
x (radius of circle)²
While the formula for the area of a triangle is:Area of Triangle =
x base of triangle x height of triangle
Hence the formula for the segment’s area is:Area of Segment = Area of sector – area of the triangle.
The formula of the area of a circle’s sector is:Area of Sector =
While the formula for the area of a triangle is:Area of Triangle =
