Ответ:Для знаходження різниці арифметичної прогресії потрібно від числа на останньому місці в прогресії (Xn) відняти перше число (X1) та помножити на кількість елементів між ними (n - 1).

Отже, різниця арифметичної прогресії буде:

d = Xn - X1 = (-47) - 2 = -49

Кількість елементів в прогресії не вказана, тому не можна точно визначити її.
