Answer:
f(n) = f(n - 1) - 13
Steps:
The given sequence is 94, 81, 68, 55, …
We can observe that the common difference between two consecitive terms is 13 since 94 - 81 = 13
Since f(1) = 94, and the form of a recursive formula is f(n) = f(n - 1) + d, we just have to plug in d = -13 in order to get f(n) = f(n - 1) - 13.
