Correct Answer: 229


Solution : Given:
5, 13, 40, 104, ?

Add the cube of consecutive natural numbers to each term to obtain the next term in the series –
5 + (2) 3 = 5 + 8 = 13; 13 + (3) 3 = 13 + 27 = 40; 40 + (4) 3 = 40 + 64 = 104; 104 + (5) 3 = 104 + 125 = 229

229 is the missing number. Hence, the first option is correct.
