Identify the Next Numbers in the Sequence: 20,155, 20,154, 20,153, ...

To complete the sequence $20{,}155, 20{,}154, 20{,}153, \ldots$, follow these steps:

• Step 1: Identify the sequence pattern.
• Step 2: Notice that each term decreases by 1 from the previous term.
• Step 3: Continue the pattern by subtracting 1 from the last known term.

Let's work through the steps:

Step 1:
The sequence given is: $20{,}155, 20{,}154, 20{,}153, \ldots$.
Step 2:
Observe that the first term $20{,}155$ is reduced to $20{,}154$, then to $20{,}153$, establishing a pattern of subtracting 1.
Step 3:
Using this pattern, find the next terms:
From $20{,}153$, subtract 1 to get $20{,}152$.
From $20{,}152$, subtract 1 to get $20{,}151$.
From $20{,}151$, subtract 1 to get $20{,}150$.

Therefore, the sequence continues as follows: $20{,}152, 20{,}151, 20{,}150$.
