If f(1)=7 and f(n)=f(n-1)+2 then find the value of f(4).

Question

Accepted Answer

Step:1 ：Given that f(1)=7 and f(n)=f(n-1)+2Step:2 ：We can use the given recursive formula to find f(4)Step:3 ：First, find f(2): f(2)=f(2-1)+2=f(1)+2=7+2=9Step:4 ：Then, find f(3): f(3)=f(3-1)+2=f(2)+2=9+2=11Step:5 ：Finally, find f(4): f(4)=f(4-1)+2=f(3)+2=11+2=13Step:6 ：So, f(4)=13Step:7 ：Check the result: f(4)=f(3)+2=11+2=13, which is consistent with the previous resultStep:8 ：Therefore, the final answer is f(4)=boxed{13}
