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: The 3 in the new number is in the hundreds place
Explanation:
Capital formation improves the conditions and methods for the production of a country. Hence, there is much increase in national income and per capital income. This leads to increase in quantity of production which leads to again rise in national income. The World Bank tracks gross capital formation, which it defines as outlays on additions to fixed assets, plus the net change in inventories. Fixed assets include plant, machinery, equipment, and buildings, all used to create goods and services. Inventory includes raw materials and goods available for sale.Oct
