\begin{gathered} f\mleft(1\mright)=36 \\ f(n)=f(n-1)-5 \end{gathered}

Step-by-step explanation

Step 1

Let


f(n)=41-5n

a) f(1)

replace the valur for n


\begin{gathered} f(n)=41-50 \\ f(1)=41-5(1)=41-5=36 \\ f(1)=36 \end{gathered}

Step 2

find f(2) and f(3)


\begin{gathered} f(2)=41-5(2)=41-10=31 \\ f(2)=31 \\ f(3)=41-5(3)=41-15=26 \end{gathered}

then, we have


\begin{gathered} f(1)=36 \\ f(2)=31 \\ f(3)=26 \end{gathered}

As you can see, the next term is the previous one minus 5,in math terms


f(n)=f(n-1)-5
