Use the image to answer the question.

An illustration shows a square with four stars along the edges, two squares attached with six stars along the outer edges; and three squares attached with eight stars along the outer edges.

The tables for a party are seated as 4 people at 1 table, 6 people at 2 tables, and 8 people at 3 tables. Use a sequence to determine how many tables would be needed for 16 people.

To determine how many tables would be needed for 16 people, we can analyze the pattern given in the problem.

The seating arrangement provided is as follows:

  • 1 table seats 4 people.
  • 2 tables seat 6 people (which suggests each table seats 3 people).
  • 3 tables seat 8 people (which suggests each table seats about 2.67 people, but we need to consider whole numbers).

From this information, we can derive a sequence based on how the number of tables increases with the seating capacity:

  1. For 1 table, seating = 4 people.
  2. For 2 tables, seating = 6 people. However, this contradicts the first statement, as traditionally, it would suggest 2 tables seating could either be 2 each (total 4) or maybe even 8 total if they are each seating 4.
  3. For 3 tables, seating = 8 people.

Now, we can simplify this by looking at the number of tables required for specific increased number of people seated. To find a consistent pattern:

  • 1 table: 4 people = 1 table
  • 2 tables: 6 people = 2 tables (or more conventional estimate could lead us to think per table 3 if we considered it equal share)
  • 3 tables: 8 people

Here let's assume that as we progress, let's just focus on deducing for higher numbers: If we note that:

  • 4 tables could seat more — could work this out along similar lines.

Let’s examine summing:

4 people at 1 table 6 people at 2 tables — the average here could involve fractional misinterpretations. 8 people at 3 tables — looks like more structured.

Continuing, we'd go: 4 tables = 10 people 5 tables = 12 people 6 tables = 14 people 7 tables = 16 people

Thus, we can conclude: To seat 16 people, you would need 7 tables according to the pattern established.
