Based on the quantum violation of bipartite Bell inequality, it has beendemonstrated that the sharing of non-locality can be demonstrated for at mosttwo sequential observers at one end and at most one-pair of observers at bothends. In this work, we study the sharing of non-locality and preparationcontextuality based on a bipartite Bell inequality, involving arbitrary $n$measurements by one party and $2^{n-1}$ measurements by other party. Such aBell inequality has two bounds, the local bound and the preparationnon-contextual bound, which is smaller than the local bound. We show that whilenon-locality can be shared only by first pair of the sequential observers, thepreparation contextuality can be shared by arbitrary pair of independentsequential observers at both ends.
