What is the mean of the numbers 2, 4, 6, 8?

Explanation:
Mean is found by adding all the numbers together and then dividing by how many numbers there are. Here, 2 + 4 + 6 + 8 equals 20, and there are 4 numbers, so 20 ÷ 4 = 5. That makes the average 5. The other options would require different totals (for example, an average of 7 would need a total of 28, an average of 4 would need a total of 16, and an average of 6 would need a total of 24), so they don’t match the calculated mean.
