Question : Directions: Select the number from among the given options that can replace the question mark (?) in the following series.
112, 101, 91, ?, 74, 67
Option 1: 81
Option 2: 85
Option 3: 80
Option 4: 82
Correct Answer: 82
Solution :
Given:
112, 101, 91, ?, 74, 67
In the above-given series, subtract consecutive natural numbers in descending order from the numbers.
112 – 11 = 101; 101 – 10 = 91; 91 – 9 = 82; 82 – 8 = 74; 74 – 7 = 67
So, 82 is the missing number of the series. Hence, the fourth option is correct.
