Answer:
0.03125
Step-by-step explanation:
Note that -32 is obtained by multiplying 128 by -1/4, and that 8 is obtained in the same way. Thus, the common ratio is -1/4, and the formula for the nth term of this sequence is
a(n) = 128(-1/4)^(n-1).
Then the 7th term is a(7) = 128(-1/4)^(7-1) = 128(-1/4)^6, or 0.03125.
