The general term for the arithmetic sequence; -13, -11, -9, -7 is Tn = -15 - 2n.
<h3>Arithmetic progression</h3>
-13, -11, -9, -7
- First term, a = -13
- Second term = -11
Common difference, d = Second term - first term
= -11 - (-13)
= -11 + 13
= 2
Therefore,
Tn = a + (n - 1)d
Where,
Tn = a + (n - 1)d
= -13 + (n - 1)2
= -13 - 2n - 2
Tn = -15 - 2n
So therefore, the general term for the arithmetic sequence; -13, -11, -9, -7 is Tn = -15 - 2n.

Answer:
z = -1
Step-by-step explanation:
7 - z / -2 - (-1)
7 - z / -2+1
7 - z / -1
-7 +z = -8
z = -1
to check the work
(-1,-1) (-2,7)
7 + 1 / -2 + 1
8 / -1
= -8
