Question

Find the digit that is not written in the same font as others. 

Hint:

In visual discrimination tasks, pay close attention to subtle details like line thickness, curvature, and the presence or absence of serifs. Systematically compare each item to a mental "baseline" established by the majority of the items.

Answer 1

Step 1: Understanding the Concept:
This question requires careful visual inspection and comparison of the typographical features (font) of each digit displayed in the image. The goal is to identify the single digit that is rendered in a style inconsistent with the rest.
Step 2: Detailed Explanation:
Let's examine the characteristics of each digit:

Digits 1, 2, 3, 4, 6, 7, 8, 9: These digits are rendered in a standard, sans-serif font. The thickness of the strokes is relatively uniform throughout each character. They appear to be from the same font family.
Digit 5: The digit '5' is stylistically different. It appears to be from a serif font family, which is characterized by small lines or strokes (called serifs) attached to the end of larger strokes. Notice the distinct serifs at the top horizontal bar and the bottom end of the curve of the '5'. None of the other digits possess these features.
The presence of serifs on the digit '5' and their absence on all other digits makes it the one written in a different font.
Step 3: Final Answer:
The digit that is not written in the same font as the others is 5.
