Hey there!

To find the mean of number sets, you will need to add up all of the numbers and divide that total sum by the amount of numbers there are. For the first set, you'll add up all of the numbers to equal 78, then divide that number by 13 to get an average of 6. For the second set, you'll add up all of the numbers to equal 132, then divide that number by 11 to get an average of 12. 

To find the difference, just subtract the smaller number, 6, from the larger number, 12, to get a difference of 6. 

Hope this helped you out! :-)
