The correct answer is A. **1. Key Concept: The General Term of an Arithmetic Progression (A.P.)** An Arithmetic Progression (A.P.) is a sequence of numbers where the difference between consecutive terms is constant. This constant difference is known as the common difference, denoted by . If the first term of an A.P. is , then the -th term, denoted by , can be found using the formula: This formula is fundamental for solving problems involving the terms of an A.P. **2.
