Answer:The answer is TRUE.Why? - Arithmetic Sequence: An arithmetic sequence is a series of numbers where the difference between any two consecutive terms is constant. This constant difference is called the common difference.- In this sequence: 3, 7, 11, 15... the common difference is 4 (7 - 3 = 4, 11 - 7 = 4, 15 - 11 = 4). Since there's a consistent common difference, the sequence is indeed an arithmetic sequence.
