Find the Predecessor: Determining the Number Before 3140

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information
• Step 2: Apply the appropriate formula
• Step 3: Perform the necessary calculations

Now, let's work through each step:
Step 1: The problem gives us the number $3140$.
Step 2: To find the predecessor, we use the formula $\text{Predecessor of } n = n - 1$.
Step 3: Subtracting 1 from $3140$, we have $3140 - 1 = 3139$.

Therefore, the predecessor of $3140$ is $3139$.
