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

1 answer

To determine how many tables would be needed for 16 people based on the information provided, we can establish a pattern from the given seating arrangements.

From the information provided:

  • At 1 table, there are 4 people.
  • At 2 tables, there are 6 people.
  • At 3 tables, there are 8 people.

We can summarize the arrangements as follows:

  • 1 table: 4 people (1 * 4 = 4)
  • 2 tables: 6 people (2 * 3 = 6)
  • 3 tables: 8 people (3 * 2.67 ≈ 8)

We can create a sequence based on the number of tables and the number of people they accommodate. Let's extract the pattern from the number of people seated:

  1. For 4 people at 1 table: 1 table
  2. For 6 people at 2 tables: 2 tables
  3. For 8 people at 3 tables: 3 tables

Notice that the seating increases by 2 people for every additional table.

We can observe this as:

  • Table 1: 4 people
  • Table 2: 6 people
  • Table 3: 8 people
  • And if we extend this logic:

Following the same logic, we could assume the next increments maintain the pattern of adding 2 additional people:

  • Table 4: 10 people (4 tables)
  • Table 5: 12 people (5 tables)
  • Table 6: 14 people (6 tables)
  • Table 7: 16 people (7 tables)

From this sequence, we see that it would take 7 tables to seat 16 people.

Thus, to accommodate 16 people, you would need 7 tables.
