16. 1 is added to the difference each time: 1 + 1 = 2 2 + 2 = 4 4 + 3 = 7 7 + 4 = 11 11 + 5 = 16 [the missing number] 16 + 6 = 22
Number is 11.1 (+1) 2 (+2) 4 (+3) 7 (+4) 11 (+5) 16 ...
Mean = 4 so sum = 4*4 = 16 The sum of the three numbers is 12 so the fourth is 16-12 = 4.
7*n-n 7*2-2=12 9*2-2=16
The mean, or average, of a data set is equal to the sum of all the data points divided by the number of data points there are. In this case, you have 11 points of data. So, this is what you'll want to do:(3+12+28+12+12+13+15+26+16+12+27)/(11) = 176/11 = 16The mean is 16.
This is what im trying to figure out
Find the missing number in the series (in red) :2 , 4 , 5, 9, 9 , 16 , 14 , ? , 20 , ….

11 15 16
Mean = 4 so sum = 4*4 = 16 The sum of the three numbers is 12 so the fourth is 16-12 = 4.
-16
17?
The missing number is 64, as you are multiplying by 4 every time.
