This is an arithmetic sequence following the formula x=n(n + 1)/2, where n is the level you want to reach, and x is the total number of Component Kits required to reach it. Most Interactive Parts follow an arithmetic sequence of 1-2-3-4-5, resulting in the total number of Component Kits needed for level 5 being 15. Upgrading requires a certain number of Component Kits per level.

Upgrades are improvements to particular Interactive Parts in Scrap Mechanic.
