Identify the recursive formula for the sequence given by the explicit formula An) = 20 - 41n - 1).
A) f(n) =
(1) = 20
(n)-f(n-1) - 4 if n > 1
OB)(n)
(1) - 20
in) - (n + 1) - 4 if n> 1
OC),(n)-
(1) - 4
(n) = f(n-1) +20 if n > 1
D) sin) -(59 ---
s(n)-1(n-1) + 20 if na 1

f(n) = {f(1)=-4

{f(n) = f(n-1) / 20 if n > 1

Or Answer B.

Step-by-step explanation:

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
