Answer 2

Answer:

4, 9/2, 5 11/2

Step-by-step explanation:

a3 =5

a+2d =5 (i)

and, a7=7

a+6d=7 (ii)

subtrating equ. (i) from (ii), we get

(a+6d) - (a+2d) = 7-5

a+6d - a-2d = 2

4d= 2

d = 1/2

on putting d=1/2 in equ. (i), we get

a+2(1/2) = 5

a+1 =5

a = 4

Now,

AP = a , a+d ,a+2d ,a+3d, a+4d

hence, 4, 9/2, 5 11/2
