Question : Directions: Which of the following numbers will replace the question mark (?) in the given series?
270, 241, 212, ?, 154, 125
Option 1: 198
Option 2: 186
Option 3: 183
Option 4: 192
Correct Answer: 183
Solution :
Given:
270, 241, 212, ?, 154, 125
Subtract 29 from the previous number, to get the required missing number in the series –
270 – 29 = 241; 241 – 29 = 212; 212 – 29 = 183; 183 – 29 = 154; 154 – 29 = 125
So, the required missing number in the series is 183. Hence, the third option is correct.
