10, 26, 74, 218, 654, 1946, 5834

  • A.26
  • B.74
  • C.218
  • D.654
  • E.1946

Answer: D

Correct answer: 654

Each term should be three times the one before, less four: \( 3(10)-4=26 \), \( 3(26)-4=74 \), \( 3(74)-4=218 \), and then \( 3(218)-4=650 \). The series gives 654 instead, so that is the wrong one; from 650 the rule resumes with 1946 and 5834.
