💡 Answer & Deep Explanation
Let’s dive into this puzzle and see what’s really going on! 🔍
The missing number is 36! Here is how the pattern works step by step so you can easily see the logic behind it.
If you look closely at each pair of numbers, the secret formula is to add the two numbers together and then multiply that total by the very first number. In simple math terms, if your numbers are A and B, the pattern follows the equation: A × (A + B).
Let us test this rule on the first line:
The numbers are 2 and 3. First, add them together to get 5 (2 + 3 = 5). Next, multiply that sum by the first number, which is 2. So, 2 × 5 gives us 10.
Now let us verify it on the second line:
The numbers are 3 and 4. Add them together to get 7 (3 + 4 = 7). Then, multiply by the first number, 3. So, 3 × 7 gives us 21.
Finally, we apply this exact same logic to find our missing answer:
The numbers are 4 and 5. Add them together to get 9 (4 + 5 = 9). Now, multiply that result by the first number, which is 4. That leaves us with 4 × 9 = 36.
That is all there is to it! The solution to this number puzzle is 36.
