More correctly in Maths. it is the MEAN. Hence mean -= (12 + 16 + 23) / 3 means = 51/3 mean = 17 .
It is 15, the number halfway between the two middle numbers.
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
16/25 is greater than 12/23

More correctly in Maths. it is the MEAN. Hence mean -= (12 + 16 + 23) / 3 means = 51/3 mean = 17 .
To get the (mean) average, add them up and divide by 3 [since there are 3 numbers]: 12 + 16 + 23 = 51, and 51 ÷ 3 = 17.

It is 15, the number halfway between the two middle numbers.
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
16/25 is greater than 12/23
The median is 19.
