Per NCERT, the RECURSIVE rule of the AP 11, 8, 5, 2, ... is which formula?
At₁ = 11, tₙ = tₙ₋₁²
Bt₁ = 11, tₙ = 2 × tₙ₋₁
Ct₁ = 11, tₙ = tₙ₋₁ − 3 for n ≥ 2
Dt₁ = 11, tₙ = tₙ₋₁ + 3 for n ≥ 2
Answer & Solution
Correct answer: C. t₁ = 11, tₙ = tₙ₋₁ − 3 for n ≥ 2
Per NCERT, common difference d = −3, so the recursive rule subtracts 3 each step.
