Which of the following numbers will replace the question mark (?) in the given series?
5, 24, 46, 74, 111, 160, 224, ?

5, 24, 46, 74, 111, 160, 224, ? 

Logic :The differences between consecutive terms in this sequence are increasing and double difference is 3, 6,9, 12, 15, 18..

24 - 5 = 19,     22 - 19 = 3

46 - 24 = 22,       28 - 22 = 6

74 - 46 = 28,       37 - 28 = 9

111 - 74 = 37,      49 - 37 = 12 

160 - 111 = 49,     64 - 49 = 15 

224 - 160 = 64,    x - 64 = 18 

So =  64 + 18 = 82

Thus, the next number in the sequence is =224 + 82 = 306 

Thus, the correct answer is (D) 306
