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 + 7= 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.
