Complete the Sequence: Finding the Pattern in 480,280, 480,290, ...

Let's proceed step-by-step to find the pattern in the sequence:

• Step 1: Identify the sequence

  The sequence begins with $480{,}280$ and $480{,}290$.

• Step 2: Determine the common difference

  Subtract the first term from the second term: $480{,}290 - 480{,}280 = 10$. The common difference is $10$.

• Step 3: Apply the common difference to find the next terms
  • Add $10$ to the second term: $480{,}290 + 10 = 480{,}300$.
  • Add $10$ to get the next term: $480{,}300 + 10 = 480{,}310$.
  • Add $10$ again: $480{,}310 + 10 = 480{,}320$.

Therefore, the next terms in the sequence are $480{,}300,\ 480{,}310,\ 480{,}320$.

This matches choice 4, given the specified answer options.

Thus, we conclude that the sequence continues with $\textbf{480,300,\ 480,310,\ 480,320}$.
