Ready for a fresh challenge that puts your visual logic to the test? In this puzzle, three diagrams of overlapping circles are paired with numbers—but the third is left blank. Your task: count the exact points where circle borders intersect and deduce the missing digit. Many solvers mistake regions for crossings or rush through the scan, so we’ll guide you step by step. You’ll learn how to avoid common errors, spot every intersection, and arrive confidently at the correct number. Dive in, sharpen your focus, and share your answer and reasoning in the comments below!

Which Number Is Missing?

At first glance, these circle diagrams might look like simple Venn‐style shapes. But pay close attention—each overlapping region holds a secret count. Questions like “Which number is missing?” push you to look beyond the obvious. Can you find the pattern before scrolling down to the answer?

Common Pitfalls: Why Solvers Sometimes Slip Up

• Overlooking Intersection Points: Many people focus on whole circles and forget to count where they overlap.
• Counting Regions, Not Intersections: It’s easy to mistakenly tally each lens-shaped region instead of the actual intersection points (where exactly two lines cross).
• Rushing Through: A quick glance rarely suffices—these little junctions demand a careful, deliberate eye.

Avoid these mistakes by zeroing in on the exact points where circle outlines cross.

Step-by-Step Solution: Mapping Overlaps to Numbers

Follow these steps to uncover the logic:

Examine the First Diagram (Two Overlapping Circles):

• There are 2 intersection points where the circles’ borders cross.
• Hence, it is labeled – 2.

Check the Second Diagram (Three Circles in a Row):

• Count every point at which any two circle outlines intersect. You’ll find 4 such crossings.
• That diagram matches – 4.

Apply the Pattern to the Third Diagram (Three Circles in a Triangle):

• Carefully trace each circle’s border and mark every crossing with another border.
• You will discover 6 distinct intersection points.

Conclude the Missing Number:

• By the same rule, the third diagram corresponds to – 6.
