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
Answer:
D, scholarships and grants
Explanation:
Scholarships and grants are essentially free money. Therefore, they're generally what one would look at first when trying to pay for a higher education.
Answer:
Behavior theory.
Explanation:
Behavioral learning is an important theory that helps to understand the behavior of humans. It is also known as behaviorism or behavioral psychology that helps to understand the environment that causes people to behave in certain ways.
So, a teacher whose student is performing poor in class, can understand his behavior with the help of behavioral theory. She will be able to examine the student's environment and know what has caused him to perform poor.
Therefore, option E is correct.
Lines that intersect at a single point.
The other incorrect choices:
-Parallel lines have no solution because they don’t intersect.
-Identical lines have infinite solutions because they touch at all times.
-the y intercept would have an x value of 0, however it’s 2.
