What is f(5)? Given f(n+1)=f(n)-2 , f(1)=18

F(5)= 10

Step-by-step explanation:

f(2)=f(1)-2

    = 18-2

f(2)=16

f(3) = f(2)-2

      =16-2

f(3)=14

f(4)=f(3)-2

     =14-2

f(4)=12

f(5)=f(4)-2

     =12-2

f(5)=10

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
