Three of the following four numbers are alike in a certain way and one is different. Select the number that is different from the rest.

165

170

195

Let’s break it down:

- 165: The sum of its digits is 1 + 6 + 5 = 12.

- 170: The sum here is 1 + 7 + 0 = 8.

- 195: Add up its digits: 1 + 9 + 5 = 15.

- 90: Digit sum? 9 + 0 = 9.

Look again: 165, 195, and 90 are all divisible by 15.

- 165 ÷ 15 = 11

- 195 ÷ 15 = 13

- 90 ÷ 15 = 6

But 170 ÷ 15 = 11.33… (not a whole number.)

So, the odd one out is 170.

Option 2: 170 is the correct answer.
