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 



Recall that 

Correlation- a measure of association between two variable.

Okay, think of an essay or paragraph as like stating your opinion. Here’s how to break it down so it’s a little easier:
Paragraph 1 - Introduction.
Provide background information on the topic. Give about 1-2 sentences on what the topic is about, and for the 3rd sentence, put in a statement that IS your argument.
For example, “French fries are the best food ever because they are delicious.”
Paragraph 2 - Conflict.
Elaborate on your argument/thesis statement. Since that seems to be your conflict, describe something hard you’ve been through. What was hard about it? How did it affect you?
Paragraph 3 - Response
Elaborate more on how the conflict affected you personally. If you can, try to connect it to a bigger picture or theme.
For example, “I broke my leg in middle school as a result of a basketball injury. Therefore, we should eliminate school sports because they cause injuries.”
It’s a reach, but that’s the entire point of connecting to a bigger theme.
Paragraph 4 - Explain Response
Here is where you’re going to connect your response in paragraph 3 to a bigger picture. Talk about the outcome and effect you showed in paragraph 3.
The questions mentioned should help you- break it down in a way that you understand. I tried to simplify this for you in the easiest way possible, I hope it helps and good luck :)
