Answer:
-31
Step-by-step explanation:
If we continue to subtract 5 from the previous term, the sequence continues ...
4, -1, -6, -11, -16, -21, -26, -31, -36, ...
The 8th term is -31.
_____
This is an arithmetic sequence with first term a1 = 4 and common difference d = -5. The general term (an) of such a sequence is ...
an = a1 +d(n -1)
Filling in the values for this sequence, the general term is ...
an = 4 -5(n -1)
Then the 8th term is ...
a8 = 4 -5(8 -1) = 4 -35
a8 = -31
