Adding of List element in Neo4j using APOC

Neo4j Graph Platform Procedures & APOC

I'm new to Neo4j and wanted to perform vector/list related operations.

Going through APOC library and documentation.

Things which worked from me but is not scalable:
UNWIND(apoc.coll.zip([1,2,3], [4,5,6])) as output
RETURN COLLECT(apoc.coll.avg(output))

OUTPUT is [2.5, 3.5, 4.5]

The catch is, number of list is dynamic in my case and lenght of each list is expected to be of 300 elements.

Problem to solve is [1, 2, 3], [3, 4, 5], [4, 5, 6], .... [n1, n2, n3]
Output: [(1+3+4+..+n1)/n, (2+4+5+..+n2)/n, (3+5+6+..+n3)/n]

The size of each list is same.

I'm also open for any other library which could achieve the same functionality.

Neo4j Desktop Graph version: 3.5.18
APOC LIbrary: 3.5.0.12

Thanks in advance!
