Answer 2

Label them A , B, and C.

Balance A and B.
If they balance out, then C must be the odd-one-out

If one is heavier (Without loss of generality, suppose A is heavier)
then take out A, replace it with C.

If C balances with B, then A is the odd-one-out.
If C is also heavier than B, then B is the odd-one-out
