What is the common difference in the following arithmetic sequence? 2/3, 1/6, -1/3,-5/

Common difference

Step-by-step explanation:

We have general form of arithmetic sequence

            a, a+d, a+2d, a+3d ...................

Here it is given that the sequence is

            2/3, 1/6, -1/3,-5/6....

Comparing we will get

So common difference

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

51-50
