Arithmetic Sequence: What Number Comes Before 7010?

To solve this problem, we'll use the concept of finding a predecessor, which involves simple arithmetic subtraction:

• Step 1: Identify the given successor number, which is 7010.
• Step 2: Subtract 1 from this successor number to find the predecessor.

Now, let's work through each step:
Step 1: We have the number 7010 as the successor.
Step 2: Since the number before 7010 is its predecessor, we calculate:
$7010 - 1 = 7009$.

Therefore, the number immediately before 7010 is $7009$.
