Hey @Amit, Sequences are the smallest type of project and they act as a single block activity. The reason why Sequences are also known as Single Block Activity is that Sequences do not use connectors, so whatever activities you add inside a sequence they get executed one after the other and they all act together like a single block.They are suitable to linear processes as they enable you to go from one activity to another seamlessly. They can be reused again, as a standalone automation or as part of a state machine or flowchart.
For example, you can create a Sequence to take information like first name, last name and favorite color etc of a user by showing multiple input dialog activities one after the other, and finally showing all the outputs together.
