Answer:
Step-by-step explanation:
80
Answer:
8*2^(n-1)
Step-by-step explanation:
This is a geometric sequence since we multiply from the previous term.
a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.
The first term is 8, so we have
a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)
1 foot = 12 inches
12 1/2 or 12.5 inches
18 and 3/4 or 18.75 X 12= 225
The ratio is 12.5:225 or to simplify 1:18.
