Answer:
see explanation
Step-by-step explanation:
Given the recursive formula  =
 =  and
 and 
 = 2
 = 2  =
 =  , then
, then
 =
 =  ( multiply both sides by 4 )
 ( multiply both sides by 4 )
a₃ = 4 ×  = 9
 = 9
 = 9 ( multiply both sides by 4 )
 = 9 ( multiply both sides by 4 )
a₂ = 36
 = 36 ( multiply both sides by 4 )
 = 36 ( multiply both sides by 4 )
a₁ = 144
The first 4 terms are
144, 36, 9, 2

Answer: 0
Step-by-step explanation: In order to identify the <em>y-intercept</em> of this equation, we want to get this equation into slope-intercept form which is more commonly known as y = mx + b form.
The problem is our equation doesn't match up quite so well with the formula y = mx + b. Our slope or <em>m</em> which is represented by the coefficient of the <em>x</em> <em>term</em> is clearly +4 but what is our y-intercept or b?
Well y = 4x can be thought of as y = 4x + 0 so you can see that our b or y-intercept equals 0.

0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.
![\begin{array}{ccll} \%&amount\\ \cline{1-2} \frac{1}{2}&250\\[1em] 100&x \end{array}\implies \cfrac{~~ \frac{1}{2}~~}{100}=\cfrac{250}{x}\implies \cfrac{1}{200}=\cfrac{250}{x}\implies x = 50000](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccll%7D%20%5C%25%26amount%5C%5C%20%5Ccline%7B1-2%7D%20%5Cfrac%7B1%7D%7B2%7D%26250%5C%5C%5B1em%5D%20100%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B~~%20%5Cfrac%7B1%7D%7B2%7D~~%7D%7B100%7D%3D%5Ccfrac%7B250%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B1%7D%7B200%7D%3D%5Ccfrac%7B250%7D%7Bx%7D%5Cimplies%20x%20%3D%2050000)
