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

Answer: Ang eleksiyon o halalan (election) ay isang pormal na proseso ng pagpapasiya kung saan ang isang populasyon ay pumipili ng mga indibidwal na hahawak ng isang publikong opisina. Ang mga halalan ang karaniwang mekanismo kung saan ang modernong kinatawan ng demokrasya ay isinasagawa simula ika-17 siglo. Ang mga halalan ay maaaring humalal ng sangay na ehekutibo, mga miyembro ng lehislatura, at minsan ay ng hudikatura gayundin ng mga miyembro ng pangrehiyon at lokal na gobyerno.
