Find missing figures:        214 (17) 325           157 (?) 412

Let's determine the missing number represented by the question mark (?) in the sequence:

\[
214 \, (17) \, 325 \quad \text{and} \quad 157 \, (?) \, 412
\]

### Analyzing the Pattern

The pattern we observe is that there are three numbers, with the middle number in parentheses. We need to find a relationship between these numbers. 

#### Step 1: Understand the given pattern

Let's consider the first set: **214 (17) 325**.

To find the missing pattern, let's observe potential operations:

1. The number in parentheses **(17)** might represent a specific mathematical operation involving 214 and 325.

2. Let's try checking a possible arithmetic operation:

\[
\text{Middle number} = \left(\text{some operation with 214 and 325}\right)
\]

#### Hypothesis: Check for a Difference or Sum Relationship

1. **Check the difference between the numbers:**

\[
325 - 214 = 111
\]

Now, observe that:

\[
17 = \frac{111}{6.5}
\]

It doesn't form a clear whole number. So, let's check other potential operations.

#### Step 2: Test the Second Set for a Similar Pattern

Now consider the second set: **157 (?) 412**.

Similarly, we might check the difference between 412 and 157:

\[
412 - 157 = 255
\]

### Conclusion

The relationship may indicate the missing number (?) could relate similarly based on factors or even number sums but to precisely guessing unique, consistent formed pattern unknown directly via this or 18th matching let’s see request confirms otherwise.
