Problem

Akamai engineers need to validate a generated sequence of service positions against metadata for Akamai delivery products. Write a PostgreSQL query that generates the first 120 elements, joins each element to its corresponding product, and returns only the 100th element.

Requirements

Generate integer positions from 1 through 120 using PostgreSQL generate_series.
Map positions cyclically to service IDs 1 through 4 and join them to akamai_products.
Return the 100th position, its service ID, product name, and product family.
Preserve the requested position explicitly with an ORDER BY clause.
