Applying what we know from the pattern of multiplying by 10, add a zero to 12.

Notice that each number in the pattern has one more zero on the end than the number before it.
Remember, the product of a number multiplied by 10 is that number with a zero on the end.
So, each number in the pattern is the previous number times 10.

The first number in the pattern is 2.
The second number in the pattern is 20, or 2 × 10.
The third number in the pattern is 200, or 20 × 10.
The fourth number in the pattern is 2,000, or 200 × 10.

So, following this pattern, the next number would be 20,000, or 2,000 × 10.

Applying what we know from the pattern of multiplying by 100, add two zeros to 12.

Notice that each number in the pattern has two more zeros on the end than the number before it.
Remember, the product of a number multiplied by 100 is that number with two zeros on the end.
So, each number in the pattern is the previous number times 100.

The first number in the pattern is 2.
The second number in the pattern is 200, or 2 × 100.
The third number in the pattern is 20,000, or 200 × 100.

So, following this pattern, the next number in the pattern would be 2,000,000, or 20,000 × 100.
