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?
From the given information, we can observe the following pattern:
For 1 table, there are 4 people.
For 2 tables, there are 6 people.
For 3 tables, there are 8 people.
We can see that the number of people per table is increasing by 2 each time.
So, for 16 people:
Number of tables = (Number of people - 1) / 2
Number of tables = (16 - 1) / 2
Number of tables = 15 / 2 = 7.5
Since we cannot have a fraction of a table, we round up to the nearest whole number.
Therefore, for 16 people, we would need 8 tables.
