Question : Directions: Select the number from among the given options that can replace the question mark (?) in the following series. 144, 171, 200, ?, 264
Option 1: 240
Option 2: 256
Option 3: 225
Option 4: 231
Correct Answer: 231
Solution : Given: 144, 171, 200, ?, 264
Add consecutive odd numbers starting from 27 to the previous term to obtain the next term. 144 + 27 = 171; 171 + 29 = 200; 200 + 31 = 231; 231 + 33 = 264
So, 231 is the missing term in the given series. Hence, the fourth option is correct.
