Which of the following numbers will replace the question mark (?) in the given series?

28, 42, 59, 81, 110, ? ,197

Given: 28, 42, 59, 81, 110, ? 197

Logic: First difference +14, +17, +22, +29, +38, +49 pattern follows

(Double difference is 3, 5, 7, 9, 11,....)

28+14=42

42+17(14+3)=59

59+22(17+5)=81

81+29(22+7)=110

148+49(38+11)=197

So, missing number = 148

Thus, correct option is (a).
