Answer:
Z is 66. If you want an explanation, I could give it to you, FYI.
A meter = 10000 cm
30cm/1m
30/10000
=0.003
x100 (for the percent)
=0.3%
The explicit formula for this arithmetic sequence is A(n)=1/2•(-8)^(n-1)
Simplify 140/96 into 35/24 since they have the common factor 4. Then convert it to 1 whole and 11/24
