Let’s look at the three diamonds and see if we can find a pattern.
In the first diamond:
- Top: 1
- Left: 5
- Right: 5
- Bottom: 3
- Center: 6
Let’s try adding the four outer numbers:
1 + 5 + 5 + 3 = 14 → but center is 6, so that’s not it.
Maybe multiply? 1 × 5 × 5 × 3 = 75 — too big.
What if we add top and bottom, and left and right?
Top + Bottom = 1 + 3 = 4
Left + Right = 5 + 5 = 10
Then 10 - 4 = 6 → matches the center!
Let’s test this on the second diamond:
Top: 3
Bottom: 4 → 3 + 4 = 7
Left: 8
Right: 7 → 8 + 7 = 15
15 - 7 = 8 → matches the center! Perfect.
Now apply to the third diamond:
Top: 1
Bottom: 5 → 1 + 5 = 6
Left: 4
Right: 9 → 4 + 9 = 13
13 - 6 = 7
So the missing number should be 7.
Final Answer:
7
