Hi chetanjadhav3288,
welcome the Neo4j community!
I think you need to be more specific with your question for us to really help you. But maybe as a start:
There are several path finding algorithms that you can use: https://neo4j.com/docs/graph-data-science/current/algorithms/pathfinding/
But you can also look for it (less efficiently) without using algorithms by e.g.:
MATCH path = (a:Node {id: 1})-[:RELATIONSHIP_TYPE*]->(b:Node {id: 20}) RETURN path
Regards,
Elena
