Question

insert five numbers between 11 and 29 such that the resulting sequence is an Ap​

Answer 1

Step-by-step explanation:

11 _ _ _ _ _ _ 29

a1=11, a7=29

a7=a+6d=29

11+6d=29

6d=18

d=3

now at first dash use a+d =14

second dash use a+2d=17 then 3d and so on

Answer 2

Answer:

11,15.5,20,24.5,29

Step-by-step explanation:

Let the 5 terms be a-2d,a-d,a,a+d,a+2d

a - 2d = 11 -- (i)

a + 2d = 29 -- (ii)

(i) - (ii)

-4d = -18 => d = 4.5

AP = 11,15.5,20,24.5,29
