Write an equation for the nth term of the geometric sequence 6000,3000,1500,750 PLEASE HELP!!!

1 answer:

8 0

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
