Which function below represents the arithmetic sequence 3, 7, 11, 15...?
(1 point)
A.) f(n) = 4 + 3(n - 1)
B.) f(n) = 4 + 3n
C.) f(n) = 3 + 4n
D.) f(n) = 3+ 4(n - 1)
The arithmetic sequence 3, 7, 11, 15... has a common difference of 4.
The formula for an arithmetic sequence is f(n) = a + (n-1)d, where a is the first term and d is the common difference.
In this case, the first term is 3 and the common difference is 4.
So the correct function is:
D.) f(n) = 3 + 4(n - 1)
