I believe the answer is -8
Answer:
y=1
Step-by-step explanation:
Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
(-2)⁵................ => (-2)(-2)(-2)(-2)(-2)...........=> -32.
recall, minus times minus is plus, and minus times plus is minus.
