Correct Answer: 190
Solution : Given: 1, 10, 28, 55, 91, 136, ?
Add the consecutive multiples of 9 to the previous numbers, to obtain the next numbers of the series. 1 + 9 = 10; 10 + 18 = 28; 28 + 27 = 55; 55 + 36 = 91; 91 + 45 = 136; 136 + 54 = 190
So, 190 is the missing number of the series. Hence, the first option is correct.
