Answer:

[tex]f(5)=10[/tex]

Step-by-step explanation:

A sequence is defined by the recursive formula [tex]f(n+1)=f(n)-2[/tex]

If [tex]f(1)=18,[/tex] then

for [tex]n=1: f(2)=f(1+1)=f(1)-2=18-2=16[/tex]

for [tex]n=2: f(3)=f(2+1)=f(2)-2=16-2=14[/tex]

for [tex]n=3: f(4)=f(3+1)=f(3)-2=14-2=12[/tex]

for [tex]n=4: f(5)=f(4+1)=f(4)-2=12-2=10[/tex]
