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

This is very complicated Don't know but I hope you find out
Answer: The Greek astronomers thought they were looking at two different planets. Phosphorus was the"bringer of light" when it appeared as the morning star. Hesperus brought good things home as darkness arrived when it appeared as the evening star. The astronomers were influenced by their beliefs in the gods and goddesses and associated the celestial bodies with the various deities.
Explanation: Actually Phosphorus is the planet Venus when it appears as the morning star. Hesperus is the planet Venus when it appears as the evening star. Babylonian astronomers had recognized the single planet; Greek astronomers later adopted this concept. Aphrodite was the Greek goddess associated with the planet later named for her Roman counterpart, Venus.
