Question : Directions: Which number will replace the question mark (?) in the following series 17, 51, 58, 116, 123, 123, ?
Option 1: 150
Option 2: 130
Option 3: 140
Option 4: 120
Correct Answer: 130
Solution : Given: 17, 51, 58, 116, 123, 123, ?
Multiply the decreasing order of the numbers starting from 3, and add 7 alternately to the given numbers – 17 × 3 = 51; 51 + 7 = 58; 58 × 2 = 116; 116 + 7 = 123; 123 × 1 = 123; 123 + 7 = 130
So, 130 is the missing number of the series. Hence, the second option is correct.
