Answer:
7
Step-by-step explanation:
You have to put the numbers in order then find the middle number.
Numbers in order: 2,3,6,6,7,8,8,8,15
Then cross out the numbers on the end (one by one) until you get to the middle number. (If there are two numbers left once you're done then you add them then divide by 2)
