Ответ: -3, 0, 3, 6, 9, 12, 15, 18

у=-3 при х=-4, у=0 при х=-2, у=3 при х=0, у=6 при х=2, у=9 при х=4, у=12 при х=6, у=15 при х=8, у=18 при х=10

х должен быть парным так как при умножении 1,5 на парное число будет целое число, добавит три и будет всё равно целое число, а если умножать на непарное выйдет нецелое число и если мы добавим до нецелого три всё равно будет нецелое число
