The Brainliest Answer!

t7 =5t2

a+6d=5(a+d)

a+6d =5a+5d

d=4a ----- (1)

Also, t3=22

a+2d=22 -----(2)

Substituting (1) in (2) we get,

a+8a=22

9a=22

Therefore,

The A.P is

a,a+d,a+3d,---

22/9 , 110/9, 198/9, ---

a7=5(a2)

a+6d=5(a+d)

a+6d=5a+5d

6d-5d=5a-a

d=4a ....................(1)

a+2d=22

a+2(4a)=22 (since d=4a)

a+8a=22

9a=22

a=22/9

d=4a

d=4(22/9)=88/9

Therefore a=22/9 andd=88/9
