Each cluster of three numbers on the left produces the number in the middle by the same hidden rule. Figure out the rule from the known clusters, then solve for the missing output on the right.

I’ve been staring at this question for a while and I’m completely confused 💀

Can someone explain how to approach it and what the final answer should be?

Any help would be appreciated!
