Simple math quiz

 

The image you uploaded presents a simple math puzzle. Here's how to solve it:

The Puzzle

The puzzle follows a pattern where the first number is added to the product of the two numbers.

·         1 + 4 = 5: This is just a simple addition.

·         2 + 5 = 12: The previous result (5) is added to the new sum (2 + 5 = 7). So, 5 + 7 = 12.

·         3 + 6 = 21: The previous result (12) is added to the new sum (3 + 6 = 9). So, 12 + 9 = 21.

The Solution

Using the same pattern, you can solve the last problem:

1.      Find the sum of the last two numbers: 5 + 8 = 13.

2.      Add the previous result (21) to this new sum (13).

3.      21 + 13 = 34.

So, the answer is 34.

Looking at the puzzle, there's a pattern to find.

1.      The first row is 1+5=6.

2.      The second row, 2+6=14, isn't a normal sum. But if you take the previous result (6) and add it to the new sum (2+6=8), you get 6+8=14.

3.      The third row, 3+7=24. The previous result was 14. The new sum is 3+7=10. So, 14+10=24.

4.      Following this pattern for the last row, 5+11=?. The previous result was 24. The new sum is 5+11=16. So, the final answer is 24+16=40.

The answer is 40

The Solution

The pattern is to multiply both numbers by 3 and add them together. This pattern is consistent across all the given equations.

·         1+5=18 ➡️ (1×3)+(5×3)=3+15=18

·         2+7=27 ➡️ (2×3)+(7×3)=6+21=27

·         3+9=36 ➡️ (3×3)+(9×3)=9+27=36

·         5+10=45 ➡️ (5×3)+(10×3)=15+30=45

Applying the same logic to the final question:

·         4+20=? ➡️ (4×3)+(20×3)=12+60=72

The answer is 72.
