It is quite acceptable to call them 11-agon 12-agon 13-agon ..... ect but what is more important is knowing how to work out their properties.
12 11 18 14 24 17 30 20.. i think ;-) pattern: 18-12 = 6 14-11 = 3 24-18 = 6 17-14 = 3 i hope that helps.
There are probably tens of such sets. Some are: 5, 6, 7, 7, 8, 11, 13, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 15, 17, 18 5, 6, 7, 7, 7, 12, 12, 14, 15, 16, 16, 18 5, 6, 7, 7, 7, 12, 12, 14, 14, 16, 16, 18
6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.
6 + 10 + 14 + 18 = 48/4 = 12 The average of the four numbers is 12.
the average age is 14-18 or 14-17. other age ranges include 15-17 15-18 15-19 15-20 and 14-20, but the average is 14-18
