2. A restaurant has
square tables which
seat four people per
table. When two tables
are placed together, six
people can be seated.
If the restaurant staff
can only prepare 10
tables placed together,
how many guests can
you bring in the
restaurant?
3. In an arithmetic sequence, if a1 is the first
term and d is the common difference, then the
terms in the arithmetic sequence can be written
as
a1 = the first term
a2 = (a1 + d), the second term
a3 = (a1 + d) + d or a1 + 2d , the third term
a4 = (a1 + 2d) + d or a1 + 3d, the fourth term
a5 = (a1 + 3d) + d or a1 + 4d, the fifth term
The coefficient of d is one less than the
number of term n, that is (n β 1)d .
4. The nth term in an arithmetic sequence
is defined as
where:
a1 = the first term
an = the missing term
n = the number of terms
d = the common difference

6. Look for a pattern that relates the number of
tables to the number of people that can be
seated in the activity presented earlier.
1 table 2 tables 3 tables
4 guests
6 guests
8 guests
