Question
If the sum of the first p terms of an AP is q and the sum of the first q terms is p, find the sum of the first (p + q) terms.
Correct Answer
Option A is the correct answer.
Detailed Explanation
Solving the system for 2a and d leads to 2a + (p + q - 1)d = -2. Multiplying by (p + q)/2 yields S_{p+q} = -(p + q).
