29+11=40

Answer 2

The given expression is: 1 + 4 = 5, 5 + 2 = 12, 12 + 3 = 15, 6 + 21 = 27, 21 + 8 = 29, 11 + ? = ?

Let's break down the given expression step by step:

1. 1 + 4 = 5 2. 5 + 2 = 12 3. 12 + 3 = 15 4. 6 + 21 = 27 5. 21 + 8 = 29

Now, we need to find the value of 11 + ?. To find the missing value, we can continue the pattern observed in the previous steps.

6. 11 + ? = ?

Based on the pattern observed, we can see that the difference between the two numbers is increasing by 1 in each step. So, to find the missing value, we need to add 1 to the previous difference.

The previous difference is 8 - 21 = -13. Adding 1 to -13 gives us -12.

Therefore, 11 + ? = 11 - 12 = -1.

So, the missing value is -1.
