Yes they equal the same because both are 0
Step-by-step explanation:
Sequence is

If it is Arithmetic sequence,
a
2
−
a
1
=
a
3
−
a
2
=
a
4
−
a
3
& so on
In the given sum,
a
2
−
a
1
=
7
−
4
=
3
a
3
−
a
2
=
10
−
7
=
3
a
4
−
a
3
=
13
−
10
=
3
Since the difference between the successive terms is same and
hence
common difference
d
=
3
Answer:
Step-by-step explanation:
MAy yoy make it bigger
18. part 1) x equals 4d square root 5 over 5 . it's a fraction
part 2) x equals 4 square root 5 over d. it's a fraction
part 3) x equals d square root 5 over 4. it's a fraction
part 4) x equals 4d square root 5 over 5 (same as part 1)
