Answer:
Attribute
Step-by-step explanation:
Attribute is defined as the characteristic or quality of an object. When we qualify statistical data based on attributes, it is referred to as qualitative classification of data.
Example of attributes are religion, educational level, gender, color of hair,etc. A change in attribute can only be expressed qualitatively.
The recursive formula of the explicit rule an = (n + 1)² is 
where a1 = 4
<h3>How to determine the recursive formula?</h3>
The explicit formula is given as:
an = (n + 1)²
This means that:
a1 = (1 + 1)² = 4
a₂ = (2 + 1)² = 9
a₃ = (3 + 1)² = 16
Rewrite as:
a₂ = 4 + 2 * 2 + 1 = 9
a₃ = 9 + 2 * 3 + 1 = 16
Substitute a₂ = 9
a₃ = a₂ + 2 * 3 + 1 = 16
Express 2 as 3 - 1
a₃ = a₃₋₁ + 2 * 3 + 1
Express 3 as n
Evaluate the product
Hence, the recursive formula of the explicit rule an = (n + 1)² is where a1 = 4

I was gonna answer but I’m not sure and I don’t want u to get it wrong so I’m just not gonna tell u sorry
Answer:
using identity (a+b)(a-b) = a^2 -b^2
Answer:
One solution
Step-by-step explanation:
In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2
In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5
In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3
So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.
Hope this helps :)
