Correct Answer: 19
Solution : Given: 15, ?, 27, 39, 55, 75
In the above-given series, add the multiples of 4 to the previous number to obtain the next number. 15 + 4 = 19; 19 + 8 = 27; 27 + 12 = 39; 39 + 16 = 55; 55 + 20 = 75
So, 19 is the missing number of the series. Hence, the first option is correct.
