Find the Missing Value Between 407,890 and 408,200

Fill in the missing number:

$407,890 < \Box < 408,200$

To solve this problem, we will follow these steps:

• Step 1: Identify the bounds of the range from the problem statement.
• Step 2: Determine if each provided choice falls within these bounds.

Now, let's solve the problem step-by-step:
Step 1: The problem states that the number must be greater than 407,890 and less than 408,200.
Step 2: Let's evaluate each choice:

• Choice 1: $407,199$ — This is less than 407,890, so it doesn't work.
• Choice 2: $408,891$ — This is greater than 408,200, so it doesn't fit.
• Choice 3: $407,999$ — This is more than 407,890 and less than 408,200, so it fits.
• Choice 4: $407,851$ — Although this choice also fits, we must check if there's a unique answer based on missing specific criteria in complexity.

Thus, the correct number that fits the conditions given is $\mathbf{407,999}$.

Therefore, the missing number is $407,999$.
