  • Options
  • A. 14
  • B. 24
  • C. 11
  • D. 16

  • Correct Answer
  • 16 

    Explanation

    The given series is in the below pattern,we can see that
    Square root of ( First term - Third term ) = Second term
    ? Square root of ( 251 ? 107 ) = Square root of 144 = 12 = Second term
    Square root of ( Fourth term - sixth term ) = Fifth term
    ? 381 ? 125 = Square root of 256 = 16 = Fifth term
    ? Fifth term ( ? ) = 16
    Hence, 16 is the missing number in the given question.
