Which recursive rule is correct for the sequence 6, 11, 19, 30, …?

Answer and explanation

Correct answer: a₁ = 6, aₙ₊₁ = aₙ + 3n + 2

A recursive rule must reproduce the first term and every successive difference. The sequence differences are 11 − 6 = 5, 19 − 11 = 8, and 30 − 19 = 11. These increments follow 3n + 2 for n = 1, 2, and 3. Starting with a₁ = 6 gives the required sequence, so option D is correct. Options A and C give different increments, while B begins with the wrong first term.
