I saw this question on the internet, these question types are YÖS exam questions and as seen from the picture I think it belongs to YÖS questions book by Kuark publications. I tried to solve it myself but couldn't. Obviously, the resulting numbers are related to the squares, but squares of what; difference between each number, or digits, or summation of them, etc.
