Logic Level 2

Sitting at your front door, you find 5 oranges, but you are told that one orange is heavier than ever other orange, one orange is lighter than every other orange, and all the other 3 oranges have the same weight.

You are also told that the absolute difference between the heavier orange to the normal orange is equals to the absolute difference between the lighter orange and the normal orange.

You have a balance scale to measure the weights.

What is the least number of measurements needed to find both oddly weighted oranges?

Challenge: Can you try this for more oranges?
