The numbers are -12, -11, -10 and -9.
10+11+12
10, 11 and 12.
The answer is 15 because the pattern is subtract one, add two

10, 11, and 12 are the only ones.
To find the mean you would add up all the numbers 7+9+10+11+11+12 and get 60. Then divide by how many numbers you added by, in this case 6. So 60 ÷ 6 = 10. The mean would be: 10

12. This is because you add the numbers and then divide by the amount of numbers to get an average. So here we add the numbers and divide the total by 3. 10+11+15 = 36. 36/3 = 12.
10 ÷ 11 ÷ 12 = (10 ÷ 11) ÷ 12 = 5/66 = 0.07575... ≈ 0.076
