Final answer:
A function called doubles() can be created to double a number and then used in a loop to double the number 2 three times, with each result displayed on a separate line.
Step-by-step explanation:
To create a function called doubles() that doubles a number, you can define it in a programming language such as Python. Then, to double the number 2 three times, you can use a loop. Below is an example of how you could write this function and use it in a loop:
def doubles(number):
return number * 2
result = 2
for _ in range(3):
result = doubles(result)
print(result)
When you run this loop, it will double the number 2 three times, and each time it doubles the number, it will print the result on a new line.
