Answer:

Step-by-step explanation:
The given sequence is
64, 16, 4, 1



It is a geometric series because it has a common ratio
.
First term is 64.
The explicit formula of a geometric series is

where, a is first term and r is common ratio.
Substitute a=64 and r=1/4 in the above function.

Therefore, the required explicit formula is
.
Answer:
1 4/5 or 1.8 pints are white
Step-by-step explanation:
1/4 of 7 1/5 = 1/4 x 36/5 = 36/20 or 9/5, which is 1 4/5
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 42 - 7.5x
-4.5x + 7.5x = 42 - 72
3x = - 30
x = -30/3
x = -10 <===
Hope this helps!
