56, 72, 90, 110, 132, 150

  • A.72
  • B.90
  • C.110
  • D.132
  • E.150

Answer: E

Correct answer: 150

Each term should be the product of two consecutive numbers: \( 7\cdot8=56 \), \( 8\cdot9=72 \), \( 9\cdot10=90 \), \( 10\cdot11=110 \), \( 11\cdot12=132 \), and then \( 12\cdot13=156 \). The series ends with 150 instead, so that is the wrong one.
