VSAM stands for virtual storage access method :
Data in vsam is devided in blocks and rendomly any block can be accessed in that.

Sequential File:
Access of data must be sequential, so if u want to access fifth record you have to go throgh first four records.

understand it and still if u have doubt ask again.
