Question

Which recursive formula can be used to determine the total amount of money earned in any year based on the amount earned in the previous year? f(n 1) = f(n) 5 f(n 1) = 5f(n) f(n 1) = 1.05f(n) f(n 1) = 0.05f(n)

Answer 1

Answer: y = f (n 1)

Explanation:

If we count interest rate = 5%

then if he earned 'y' amount in 1st year then in 2nd year he must earned

= y + 5% of y

== 1.05 y

here, y = f(n 1)
