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 .
17 is a prime number because it’s only divisible by 1 and it’s self, so it only has 2 factors.
2n+5...a couple is two people so you need to multiply the number of couples, n, by 2 to get the total number of dancers. Then add the total number of organizers.
It appears like the 3 was distributed through the parenthesis
