This is an arithmetic sequence since there is a common difference between each term. In this case, adding
4
to the previous term in the sequence gives the next term. In other words,
a
n
=
a
1
+
d
(
n
−
1
)
.
Arithmetic Sequence:
d
=
4
This is the formula of an arithmetic sequence.
a
n
=
a
1
+
d
(
n
−
1
)
Substitute in the values of
a
1
=
2
and
d
=
4
.
a
n
=
2
+
(
4
)
(
n
−
1
)
Simplify each term.
a
n
=
2
+
4
n
−
4
Subtract
4
from
2
.
a
n
=
4
n
−
2
Substitute in the value of
n
to find the
n
th term.
a

Multiply
4
by

And if arthemetic then this is the answer.
