In the yellow puzzle it's prime number 13 (just continue in top down direction from 1st column);
In the pink puzzle it's 22 (add the 1st column number with 3rd column number then multiply by 2);
Finally last one blue puzzle it's 16 (1st column number multiply by 2, then 2nd column number multiply by 3, then sum up both results)
This is super hard.
