Among the numbers 108, 128, 135 and 153, three share a property that the fourth lacks. Choose the odd one out.

Add the digits and the tie shows itself: 1 + 0 + 8 = 9, 1 + 3 + 5 = 9 and 1 + 5 + 3 = 9, so 108, 135 and 153 all divide exactly by 9. For 128 the digits total 1 + 2 + 8 = 11, which is not divisible by 9, and indeed 9 goes 14 times into 126 and leaves 2 over. The number is the trap because it lies in the same run as the rest and looks just as orderly, being 2 multiplied by itself seven times.
