I’m positive you can’t locate the 4th object.

Ah! Now I see—you want me to identify the 4th object in the sequence:

Knife, Egg, Apple, Comb

Let’s go step by step:

1. 1st object → Knife
2. 2nd object → Egg
3. 3rd object → Apple
4. 4th object → Comb ✅

So the 4th object is the Comb.

Do you want me to explain a trick some riddles hide with this type of sequence?
