Answer: [tex]f(n) =f(1)+0.2(n-1)[/tex]

Step-by-step explanation:

Given: [tex]a_n=5+0.2(n-1)[/tex]

It is the formula of nth term [tex][a_n=a+(n-1)d][/tex] in Arithmetic progression

where 5 = First term

0.2 = common difference

To write first term , we use f(1).

nth term will be

[tex]f(n) =f(1)+0.2(n-1)[/tex]

Hence, the function form : [tex]f(n) =f(1)+0.2(n-1)[/tex]
