Detailed solution

63. 88. Go on subtracting prime numbers 19, 17, 13, 11, 7, 5 from the numbers to get the next number. So, 88 is wrong.

64. 30. Multiplly each term by 3 to obtain the next term. Hence, 30 is a wong number.

65. 104. Series is written in descending order with a difference of 9, 8 ,7, 6 and 5 respectively. Hence ,the missing number will be 104.

66. 126. Method used to from the series is :(1)³+1, (2)³+1,(3)³+1, (4)³+1 Therefore the missing number is (5)3 +1= 126.
