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 .
The percent of the jerseys :
6 : 800 = 0,75%
The coefficient represents how many quarters it is
Let x = amount invested at 8%
26000 - x = amount invested at 6%
0.08x + 0.06(26000 - x) = 1860
solving the equation you get x = 15000
and subtract that from 26000 you get 11000
8% investment = 15000
6% investment = 11000
Oooooffffffff im pretty positive that this is true
