WebAn arithmetic progression or arithmetic sequence (AP) is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression … WebMock Tests; Mock Tests; Aptitude and Reasoning; General Knowledge; Puzzles; Interviews; Technical WebDec 24, 2024 · selected Dec 24, 2024 by Bhairav.
