All the numbers are composite except the ones in bold: 18 19 20 21 22 23 24 25.
21.8Simply add them all up, and then divide by how many numbers you have.
24 + 23 + 22 + 21 + 20 + 19 + 18 + 17 + 16 + 15 + 14 + 13 + 12 + 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 300
(19+22)/2 = 20.5
The answer is 24.
