Solve This Tricky Math Riddle: Can You Crack the Pattern?

The Riddle Unveiled

At first glance, it looks like simple addition. But quickly, you'll notice something's off.

• 1 + 4 = 5 (Okay, that checks out)

• 2 + 5 = 12 (Wait, what?!)

• 3 + 6 = 21 (Now this is just getting confusing!)

• 4 + 7 = ?

The challenge is to figure out the pattern and then solve the final equation: 4 + 7 = ?

The Secret Revealed!

There are a couple of ways to approach this riddle, but the most common solution involves a cumulative addition.

How the Pattern Works

Here’s how it works:

• 1 + 4 = 5
  This is straightforward.

• 2 + 5 = 12
  Here, you take the result from the previous equation (5) and add it to the current sum (2 + 5 = 7).
  So, 5 + 7 = 12.

• 3 + 6 = 21
  Again, take the result from the previous equation (12) and add it to the current sum (3 + 6 = 9).
  So, 12 + 9 = 21.

Solving the Final Equation

Following this pattern:
Take the result from the previous equation (21) and add it to the current sum (4 + 7 = 11).
So, 21 + 11 = 32.

Did You Crack It?

Did you get it right? This riddle is a fantastic example of how sometimes, the simplest-looking problems can have a hidden complexity! It’s a great way to give your brain a quick workout.

========================================================

Pattern: For each line a + b = ? the result equals b² + a.

Check the given lines:

• $6 + 8 = 8^2 + 6 = 64 + 6 = 70$

• $3 + 7 = 7^2 + 3 = 49 + 3 = 52$

• $9 + 4 = 4^2 + 9 = 16 + 9 = 25$

So for the last one:
$1 + 5 = 5^2 + 1 = 25 + 1 = \mathbf{26}$

Answer: 26
