Q. f(n)=41−5nComplete the recursive formula of f(n).f(1)=□f(n)=f(n−1)+
Write Explicit Formulas: To find the recursive formula for the sequence, we need to express f(n) in terms of f(n−1). Let's start by writing down the explicit formula for f(n) and f(n−1).f(n)=41−5nf(n−1)=41−5(n−1)
Simplify Expression: Now, let's simplify the expression for f(n−1) to see the relationship between f(n) and f(n−1). f(n−1)=41−5(n−1) f(n−1)=41−5n+5 f(n−1)=(41−5n)+5 f(n−1)=f(n)+5
Rearrange Equation: We can now rearrange the equation to solve for f(n) in terms of f(n−1). f(n)=f(n−1)−5 This is the recursive formula for the sequence.
