Did you get it right?
Choose the tile whose two triangle colors continue every diagonal in the four-by-four porch pattern.

The Answer
The correct answer is: choice 2, the yellow-and-blue tile.
Here is why
- The upper triangle colors repeat red, yellow, blue along each row and diagonal.
- At the missing position, that progression requires yellow on the upper-right triangle.
- The lower-left triangle follows the same shifted progression and requires blue.
- Only choice 2 has the required yellow-and-blue arrangement.
Why people miss it
Several choices contain one correct color, but only one preserves both diagonal sequences at the same time.
