Question

HELP PLS 100PTS!!! Evaluate s(-19) s(n)=7-4n

Answer 1

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

Answer 2

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!!
