5824, 5242, ?, 4247, 3823

  • A.4467
  • B.4718
  • C.4856
  • D.5164

Answer: B

Correct answer: 4718

Each term is reduced by the number formed from its own first three digits: \( 5824-582=5242 \), then \( 5242-524=\mathbf{4718} \), and the rule holds on: \( 4718-471=4247 \) and \( 4247-424=3823 \).
