Answer 9

thats what i thought thanks

Answer 10

those are evenly spaced for sure, but the question, as i read it, makes no sense at all

Answer 11

let x1 ,x2, x3 be te three AM between 5 and 17 then total terms is n=5 first term is 5 and common difference is d and last term is 17 then
l=a+(n-1)d
17=5+(5-1)d
d=3
x1=a+d=5+3=8
x2=a+2d=11
x3=a+3d=14
