P(x) has the highest value in n(x) has the highest value in 15 years
A(n)=4+4(n-1)
a(n)=4+4n-4
a(n)=4n
76=4n
n=19
The sum of any arithmetic sequence (series are infinite) is:
(a+a(n))(n/2)
The average of the first and last terms times the number of terms, in this case we found that n=19 so:
19(4+76)/2=760
Answer:
-1 1/4
Step-by-step explanation:
A because the median is 0.1 and the mean is much higher
