Validation is the procedure of establishing documented evidence that provide high degree of assurance that the specific process will consistently produce a product meeting its pre-determined specification and quality attributes. This is called validation.

Verification is the comparison of results against specifications.

Dear,
Process validation: Generally 3 batches/run/cycles to be considered.
Process verification: 1 batch/run/cycle can be considered.

Thanks
