Correct Answer: 254
Solution : Given: 89, 170, 219, 244, 253, ?
Add the square of consecutive odd numbers in decreasing order starting from 9, to get the required missing number – 89 + 92 = 89 + 81 = 170; 170 + 72 = 170 + 49 = 219; 219 + 52 = 219 + 25 = 244; 244 + 32 = 244 + 9 = 253; 253 + 12 = 253 + 1 = 254
So, the missing number is 254. Hence, the first option is correct.
