An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant. In this case, the arithmetic sequence is:
60, 50, 40, ...
To find the common difference, we subtract each term from the one after it:
50 - 60 = -10
40 - 50 = -10
So, the common difference is -10.
A linear function in the form f(n) = an + b represents an arithmetic sequence, where 'a' is the common difference and 'b' is the initial term.
In this case, the common difference is -10 and the initial term is 60. So, the linear function that represents the arithmetic sequence 60, 50, 40, ... is:
f(n) = -10n + 70
Therefore, the correct answer is: f(n) = -10n + 70.
