Finding patterns in seemingly random sets of data is what cryptography is all about. Sometimes finding the questions may be harder than answering them! See if you can figure out what the heck we are talking about.
When I bought the house the safe in the wall was locked. In a drawer there was a piece of paper. It was written:

3740619285
7532084619
9746085321

3; Crypt key = 2018

What could be the four-digit key?
