| 91+9=100 100+12=112 112+15=127 = 128 is wrong 127+18=145 145+21=166 166+24=190 |

| Out of all the numbers only 100 is a perfect square. So, in the series 100 is only the odd one out. |

| 91-1 = 90. 100-1 = 99. 112-1 = 111. 128-1 = 127. 145-1 = 144. 166-1 = 165. 90, 99, 111, 144, 165 all are divisible by 3. Except 127, So 128 is odd. |

| 190 - 24(3 x 8) = 166, 166 - 21(3 x 7) = 145, 145 - 18(3 x 6) = 127 -----> Correct and 128 is wrong, 127 - 15(3 x 5) = 112, 112 - 12(3 x 4) = 100 -----> Multiples of 3 is subtracted from each number. |

| 100 could also be the answer as it's only prefect squared number in the series. | |

| When dividing numbers by 3 you will get remainder 1 but in 128 you will get remainder 2. Hope it will help. |
