Write an equation for the nth term of the geometric sequence 6000,3000,1500,750 <br> PLEASE HELP!!!
Wewaii [24]

Answer: 6000\cdot (1/2)^{n-1}

Each term is half of the previous one, so the common ratio is 1/2. Then to get from the first term to the nth term, you have to take n - 1 steps, multiplying by 1/2 each time and by 6000 to account for the first term.

i hope this helps! :D

A singing contest eliminates contestants after each round. The number of contestants that go into round n is equal to the number
dimaraw [331]

Answer:

9

Step-by-step explanation:

Since we know the number of contestants in Round 2, we could go step by step and calculate the number of remaining contestants in Round 3, then Round 4 and finally Round 5.

However, we can do it without calculating. So in Round 3, there will be:

R3 = R2^((n-1)/n), where n is number of the round

R3 = R2^(2/3)

For Round 4, the number will be:

R4 = (R2^(2/3))^(3/4)

And Round 5 will be:

R5 = ((R2^(2/3))^(3/4))^(4/5)

Threes and fives in exponents will cancel out and we'll remain only with:

R5 = R2^(2/5)

R5 = 249^(2/5)

R5 = 9.08

Rounded to the nearest integer, the number of contestants in Round 5 is 9.
