Answer:
1.2 x 10⁴
Step-by-step explanation:
12,000 has 2 places of other numbers before a spam of zeroes.
Take the numbers before zeroes and put a decimal to the left of the last digit.
Last digit is 2 so a decimal goes before 2
1.2
Count how many places the decimal moved: this number is your power of 10.
12000. --> 1.2000
It moved 4 places.
12,000 = 1.2 x 10⁴
Answer: 
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
