Question

mean of y-2,y-a,y+a,y+2a is ____.
​

Answer 1

Answer:

Y

Step-by-step explanation:

there are 4 data points

Y-2 , Y-a , Y+a , Y+2a

Mean = (Y-2) + (Y-a) + (Y+a) + (Y+2a) /4

Mean = 2Y + a -2 / 2

I think that there is a change in que,

Data points are Y-2 , Y-a , Y+a , Y+2

then mean is Y
