Step-by-step explanation:
Arithmetic:
a(n) = a +(n-1)d
a=15
d=5-15=-10
°.° a(n) = 15 +(n–1)-10
Geometric:
a(n)=a*r^(n-1)
a=15
r=5/15=1/3
a(n)=15*(1/3)^(n-1)

Answer:
Z-score = 1.18
Step-by-step explanation:
The z-score measures how many standard deviations from the mean a data is
Therefore the z score is the quotient between the difference between a value and the mean and the standard deviation

Where
μ is the mean, x is a data of the population and
is the standard deviation
In this case

Then the z-score is
