Hi,
The key difference is that a sequential patterns is only evaluated using the support, while a sequential rule is also evaluated using a measure such as the confidence. This is because even if a sequential pattern appears many times, we dont have a measure of how correlated the items in the sequential patterns are. For a sequential rule X--Y, the confidence can be viewed as the conditional probability that X is followed by Y. My explanation is very brief. Hope that it helps.
