Web16 Mar 2024 · Answer: d = -2 Step-by-step explanation: Because the sum of first n terms of any AP is in the form (d/2)n² + (a - d/2)n, where d is the common difference and a is the first term. So that the coefficient of n² is half of the common difference. Here in S_n = 4n - n², the coefficient of n² is -1, so that half of common difference is -1.
