Answer:
YES
Step-by-step explanation:
Explicit rules for arithmetic sequences follow the format
a
n
=
d
(
n
−
1
)
+
a
1
(or with a
f
(
n
)
instead of an
a
n
), where
d
represents the common difference and
a
1
represents the first term
To find the first 4 terms, plug
1
,
2
,
3
,
4
in for
n
:
f
(
1
)
=
7
(
1
−
1
)
−
10
f
(
1
)
=
7
(
0
)
−
10
f
(
1
)
=
0
−
10
f
(
1
)
=
−
10
Do the same thing for
2
,
3
,
4
The first four terms are
−
10
,
−
3
,
4
,
11
