Answer:
f(n+1) = f(n)+5
Step-by-step explanation:
So lets say
f(1)=5
f(2)=10
1+1=2 so
f(2)=f(1+1)
therefor
f(n+1)=f(n)+5 since the difference of the functions is 5
the answer is A f(n+1)=f(n)+5
we know that
An arithmetic sequence is a sequence of numbers which increases or decreases by a constant amount each term
In this problem
the sequence of numbers increase by a constant amount equal to
5
each term
so
f(2)=f(1)+5
f(3)=f(2)+5
f(4)=f(3)+5
.
.
f(n+1) = f (n) + 5
therefore
the answer is the option
f(n + 1) = f(n) + 5
