Answer: Therefore, the recursive formular is A(n) = A(n - 1) + 9

Step-by-step explanation: (n) = 2 + 9(n - 1) = 2 + 9n - 9

(n + 1) = 2 + 9(n + 1 - 1) = 2 + 9n = (2 + 9n - 9) + 9 = A(n) + 9

S(-19)=7-4(-19)
In this step, I inserted the value into the equation.
Next, evaluate.
s(-19)=83
(Multiply the -4 times -19, which gives 76, then add the 7, which gives 83)
Hope this helps!!

Answer:

APR = 416%

EAR = 5370.60%

Step-by-step explanation:

Given:

Interest rate = 7.8% per week

Now,

In an year there are total 52 weeks

thus,

The APR (Annual percentage rate) = Interest rate × Total weeks in an year

APR = 8% × 52

APR = 416%

and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1

Here,

r is the interest rate per week

n is the total weeks in an year

thus,

EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1

= ( 1 + 0.08 )⁵² - 1

= 53.7060

53.7060 × 100% = 5370.60%
