I'd say an outlier. P is separated noticably from the other points and would not considerably affect the slope of the line
Answer:
An outlier
Step-by-step explanation:
The point P is quite separate from the rest of the data.
No , the y-values of a data set cannot have both a common difference and a common ratio at the same time.
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
Thus nth term of an AP series is Tn = a + (n - 1) d
d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
Given data ,
A common difference means that the difference between any two consecutive y-values in the data set is the same. For example, if the first y-value is 3 and the common difference is 2, then the second y-value would be 5 (3 + 2), the third y-value would be 7 (5 + 2), and so on. This creates a linear relationship between the y-values.
And , a common ratio means that the ratio between any two consecutive y-values in the data set is the same. For example, if the first y-value is 3 and the common ratio is 2, then the second y-value would be 6 (3 x 2), the third y-value would be 12 (6 x 2), and so on. This creates an exponential relationship between the y-values.
Hence , a linear relationship and an exponential relationship are different, it is not possible for the y-values of a data set to have both a common difference and a common ratio at the same time.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the price of the computer be = A
Now , the regional price of the computer be = $ 1200
The sale price of the computer is = ( 5/6 ) of original price
So , the equation will be
The sale price of the computer is = ( 5/6 ) x 1200
= 5 x 200
= $ 1000
Therefore , the price of the computer is $ 1000
Hence , Alexander purchased the computer for a price of $ 1000

To find the rate of change, also known as the slope, we can use the slope formula with these two given points.
Point 1: (20, 25)
Point 2: (50, 40)
(40 - 25) / (50 - 20)
15 / 30
0.5
The rate of change of this function is $0.50 / lb.
