Solve the Sequence Puzzle: Identifying My Successor Before 2000

To determine the number that comes immediately before 2000, we can use the property of consecutive integers, which differ by exactly 1.

• Step 1: Identify the given number, which is 2000, and recognize we need the number preceding it.
• Step 2: Subtract 1 from 2000, because consecutive numbers differ by one.
• Step 3: Perform the subtraction: $2000 - 1 = 1999$.

Thus, the number that comes right before 2000 is $1999$.
