Стале число, у яке змінюються члени арифметичної прогресії, називається різницею прогресії. Ця назва походить від того, що кожен член прогресії отримується додаванням до попереднього члена однієї і тієї ж самої сталої величини, яка і є різницею прогресії. Наприклад, у прогресії 2, 5, 8, 11, 14 стала різниця прогресії дорівнює 3, оскільки кожен наступний член отримується додаванням 3 до попереднього.
