the total of the first 11 numbers is (11)(20) or 220, and the total of the other 3 numbers is 3(48) or 144
so the total is 220+144 = 364
and there are 14 numbers
the average of all of them is 364/14 = 26
so the total is 220+144 = 364
and there are 14 numbers
the average of all of them is 364/14 = 26
