The arithmetic sequence 60, 50, 40... has a common difference of -10. This means that each term decreases by 10.
Looking at the linear functions provided:
1. f(n) = -10n + 50
2. f(n) = -10n + 70
3. f(n) = 10n + 70
4. f(n) = 10n + 50
The linear function that represents the arithmetic sequence 60, 50, 40... is f(n) = -10n + 70. This is because it decreases by 10 each time and starts at 70, which corresponds to the initial term of 60 in the sequence.
