Concept:The sequence follows a decreasing pattern where the subtracted values decrease by 2 each time.Explanation:Find the differences between consecutive terms:588−563=25563−540=23540−519=21The differences form: 25,23,21,…Each difference is 2 less than the previous one.So the next differences are 19,17,15.Thus, 519−19=500.Check: 500−17=483and 483−15=468.
