What is the mean of 5 observations and 8 variates?

The mean of 25 observations is 27. 9. The mean of 5 observations is 15. If the mean of first three observations is 14 and that of the last three is 17, find the third observation. The third observation = 93 – 75 = 18. 10. The mean of 8 variate is 10.5. If seven of them are 3, 15, 7, 19, 2, 17 and 8, then find the 8th variate.
