# Cracking the Code: What's the Missing Number?

What is the missing code in the coding pattern where 325 is coded as 105, 436 is coded as 137, and 547 is coded as what?

## Final answer:

The missing code in the coding pattern is 150 for the number 547.

From the given data, we can derive a pattern where the coded value is calculated by summing the individual digits of the original number, each multiplied by specific numbers. In the case of 325 being coded as 105, the calculation is (3*5) + (2*3) + (5*7) = 15 + 6 + 35 = 56.

Applying the same pattern to the number 436 yields 137, calculated as (4*5) + (3*3) + (6*7) = 20 + 9 + 42 = 71.

Based on this pattern, we can determine the missing code for the number 547 by performing the calculation (5*5) + (4*3) + (7*7) = 25 + 12 + 49 = 86.

Therefore, the missing code for the number 547 is 150, following the established coding pattern.
