Just do pythagorean theorem. The answer is the square root of 75
A bell curve describes a random distribution where at either end is a low amount with the middle representing a higher amount of points.
So at either ends are “extremes” were someone scored really low or really high. The middle presents the average where most people will score
Here is your function graphed
The firs term
A(1)=-6+(1-1)(6)
A(1)=-6+(0)(6)
A(1)=-6
The fourh term
A(n)=-6+(n-1)(6)
A(4)=-6+(4-1)(6)
A(4)=-6+(3)(6)
A(4)=-6+18
A(4)=12
The tenth term
A(10)=-6+(10-1)(6)
A(10)=-6+(9)(6)
A(10)=-6+54
A(10)=48
Answer:
D. -6,12,48
