Construct an explicit rule in function notation for the arithmetic sequence represented in the table. Then interpret the meaning of a specific term of the sequence in the given context.
The table shows f(n), the distance, in miles, from the store after Mila has traveled for n hours.

Determine the value of f(18) and tell what it represents in this situation.
f(18)=
So, Mila is
miles from the store after 18 hours.
