1. The problem asks how to get the number 12 from 172 and then find the equivalent for 194. 2. Let's analyze the relationship between 172 and 12. One way is to find a function or operation that transforms 172 into 12. 3. Check if 12 is the sum of the digits of 172: $1 + 7 + 2 = 10$, which is not 12. 4. Check if 12 is the difference between digits: $7 - 1 = 6$, $7 - 2 = 5$, no 12. 5. Check if 12 is the product of digits: $1 \times 7 \times 2 = 14$, no. 6. Check if 12 is the difference between 172 and a number: $172 - 160 = 12$, so subtracting 160 gives 12. 7. Alternatively, check if 12 is the remainder when dividing 172 by some number: $172 \div 13 = 13$ remainder $3$, no. 8. Another approach is to consider the sum of digits squared: $1^2 + 7^2 + 2^2 = 1 + 49 + 4 = 54$, no. 9. Since no direct arithmetic relation is obvious, assume the operation is subtracting 160: $172 - 160 = 12$. 10. Apply the same operation to 194: $194 - 160 = 34$. Final answer: The number corresponding to 194 is 34 if the operation is subtracting 160.
