To find the average (mean) of a set of numbers, you add all numbers then divide by how many numbers given. Since you have positive and negative numbers, add all the positive numbers together, then add all the negative numbers.
95 + 29 + 20 +12 = 156 and -47 + -67 = -114
Subtract: 156 + -114 = 42
Divide: 42/6 = 7
Average (mean) is 7
