Complete the Sequence: An Arithmetic Progression with Million Multiples

To solve this problem, we will follow these steps:

• Step 1: Identify the pattern by examining the given numbers in the sequence.
• Step 2: Calculate the difference between the first two numbers in the sequence.
• Step 3: Use this difference to find the next numbers in the sequence.

Now, let's work through each step:

Step 1: The given sequence starts with the numbers $1,000,000$ and $2,000,000$.

Step 2: We calculate the difference between these numbers: $2,000,000 - 1,000,000 = 1,000,000$ This suggests that each term in the sequence increases by $1,000,000$.

Step 3: Using this pattern, we add $1,000,000$ to the last known term to find the next terms: $2,000,000 + 1,000,000 = 3,000,000$ $3,000,000 + 1,000,000 = 4,000,000$ $4,000,000 + 1,000,000 = 5,000,000$ Thus, the next terms in the sequence are $3,000,000$, $4,000,000$, and $5,000,000$.

Therefore, the solution to the problem is:
$3{,}000{,}000,\ 4{,}000{,}000,\ 5{,}000{,}000$.
