Find the three arithmetic means between ­-4 and 16.

Step-by-step explanation:

let the three arithmetic means is x,yand z

-4,x,y,z,16

we know that common difference is same in A.P

x+4=y-x

2x=y-4 (1)

y-x=z-y

2y=z+x (2)

z-y=16-z

2z=16+y (3)

after solving equation (1),(2)and(3) we get

x=1

y=6

z=11

step-by-step explanation:

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
