In both species repeated pairing of a CS and US eventually produces a CR in response to the CS alone. In the sea-slug this is a very direct process, in the species we have been discussing in these lectures - rats, dogs, humans and so on - I hope you have seen that it is far from being so simple.
Answer:

Explanation:
Given


Each term after the second term is the average of all of the preceding terms
Required:
Explain how to solve the 2020th term
Solve the 2020th term
Solving the 2020th term of a sequence using conventional method may be a little bit difficult but in questions like this, it's not.
The very first thing to do is to solve for the third term;
The value of the third term is the value of every other term after the second term of the sequence; So, what I'll do is that I'll assign the value of the third term to the 2020th term
<em>This is proved as follows;</em>
From the question, we have that "..... each term after the second term is the average of all of the preceding terms", in other words the MEAN

<em>Assume n = 3</em>

<em>Multiply both sides by 2</em>


<em>Assume n = 4</em>


Substitute 



Assume n = 5


Substitute
and 



<em>Replace 5 with n</em>

<em>(n-1) will definitely cancel out (n-1); So, we're left with</em>

Hence,

Calculating

The Warren Court refers to the Supreme Court of the U.S. during the period when Earl Warren served as Chief Justice. Warren replaced the deceased Fred M. Vinson as Chief Justice in 1953, and Warren remained in office until he retired in 1969. Warren was succeeded as Chief Justice by Warren Burger.
Warren led a liberal majority that used judicial power in dramatic fashion, to the consternation of conservative opponents. The Warren Court expanded civil rights, civil liberties, judicial power, and the federal power in dramatic ways.
The court was both applauded and criticized for bringing an end to racial segregation in the United States, incorporating the Bill of Rights, i.e. including it in the 14th Amendment Due Process clause, and ending officially sanctioned voluntary prayer in public schools. The period is recognized as the highest point in judicial power that has receded ever since, but with a substantial continuing impact.
Prominent members of the Court during the Warren era besides the Chief Justice included Justices William J. Brennan, Jr., William O. Douglas, Hugo Black, Felix Frankfurter, and <span>John Marshall Harlan II</span>
