Correct Answer: 209
Solution :
Given:
254, 251, 245, 236, 224, ?
Subtract the consecutive multiples of 3 from the previous number to obtain the next number of the series.
254 – 3 = 251; 251 – 6 = 245; 245 – 9 = 236; 236 – 12 = 224; 224 – 15 = 209
So, 209 is the missing term of the series. Hence, the second option is correct.
