What should come in place of the question mark (?) in the given series?
86, 97, 73, 82, 60, 67, 47, 52, ?

Given: 86, 97, 73, 82, 60, 67, 47, 52, ?

1st series: 86, 73, 60, 47, ?

2nd series: 97, 82, 67, 52

Logic for 1st: Numbers are decreasing - 13 place.

86 - 13 = 73

73 - 13 = 60

60 - 13 = 47

47 - 13 = 34

So, the missing term is 34.

Logic for 2nd: Numbers are decreasing - 15 place.

97 - 15 = 82

82 - 15 = 67

67 - 15 = 52

Thus, correct option is (b).
