What is the 12th term of the linear sequence below?
13,7,1,-5,-11

The 12th term is - 53

Or if we observe there is difference of - 6 in every two consecutive term so we can get the next term by adding - 6. And repeat the process until we get the 12th number.

6th no. -11+-6=-17

7thh -17+-6=-23

8th -23+-6=-29

9th -29+-6=-35

10th -35+-6=-41

11th -41+-6=-47

12th -47+-6=-53

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
