Answer 1

first arrange it into ascending or descending order.

If we arrange in ascending order, it will be as: 8,8,9,9,9,10,1011,12,12,13,14,15,15,16,18

we see that there are 16 terms.

we will separate 7 numbers from both side and average of 8th and 9th term will be the answer

8th term = 11

9th term = 12

average = 11 + 12/2

= 23/2 = 11.
