🧠 Can You Solve This Reasoning Test? Find the Missing Number

At first glance, this puzzle looks like a simple number sequence, but there is a clever pattern hidden in the arrangement.

The numbers around the circle are:

4, 5, 6, 8, 20, 30, 42, ?

Your challenge is to find the missing number.

🔍 Look at the Opposite Numbers

Instead of reading the numbers clockwise, compare the numbers that sit opposite each other.

Start with 4.

The number directly opposite 4 is 20:

4 × 5 = 20

Now look at 5. Its opposite number is 30:

5 × 6 = 30

Next, 6 is opposite 42:

6 × 7 = 42

Do you see the pattern?

Each number is multiplied by the next consecutive number to produce its opposite.

So we have:

• 4 × 5 = 20
• 5 × 6 = 30
• 6 × 7 = 42
• 8 × 9 = ?

Therefore:

🎯 8 × 9 = 72

✅ The Missing Number Is 72

The answer is 72.

What makes this puzzle interesting is that the pattern isn’t obvious if you simply follow the numbers around the circle. The key is to notice the opposite pairs.

Final Answer: 72
