It is: 21+18+15 = 54 and 54/3 = 18 which is the mean average
It is: 14+15+22+21 = 72/4 => 18 which is the mean average
The average is 15.
The average of 6, 15 and m is (6 + 15 + m) / 3 = (21 + m)/3 = 7 + m/3
something okay how i meant to know ? :)

36 - 21 = 1536 - 21 = 1536 - 21 = 1536 - 21 = 15

21*15 is equal to 315 21 x 15 = 315

There is no such data set for 7 numbers. With the maximum at 35 and the range 20, the mode (average) will always be more than 21, even with the lowest numbers possible. e.g. 15 15 15 24 24 24 35 sums to 152, which is 5 higher than the necessary 147 (21 x 7) So you need at least 11 numbers such as 15 15 15 15 15 24 24 24 24 25 35, keeping 24 as the median and the average 21 (231/11).
