Correct Answer: 134
Solution : Given: 149, ?, 114, 89, 59, 24
Subtract multiples of 5 starting from the third multiple to get the next term – 149 – (5 × 3) = 149 – 15 = 134; 134 – (5 × 4) = 134 – 20 = 114; 114 – (5 × 5) = 114 – 25 = 89; 89 – (5 × 6) = 89 – 30 = 59; 59 – (5 × 7) = 59 – 35 = 24
So, the missing number is 134. Hence, the fourth option is correct.
