Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 5, 20, 60, 240, 720, ?
Option 1: 2580
Option 2: 2880
Option 3: 2160
Option 4: 2675
Correct Answer: 2880
Solution : Given: 5, 20, 60, 240, 720, ?
To get the required missing number in the series, multiply the number by 4 and 3 alternatively – 5 × 4 = 20; 20 × 3 = 60; 60 × 4 = 240; 240 × 3 = 720; 720 × 4 = 2880
So, the required missing number in the series is 2880. Hence, the second option is correct.
