hi mate it is not a a.p

common difference differs

plz mark as brainlist

Step-by-step explanation:

a1 = - 1.2 , a2 = -1.3 ,a3= - 5.2 , a4= -7.2

d= a2-a1

     = - 1.3 -(-1.2)

    d = - 0.1

d= a3-a2

     = -5.2-(-1.3)

       d =  - 3.9

d= a4 - a3

    = - 7.2 -( - 5.2)

   d=  2

common difference  must be same in the series will be a.p

if common difference is not same the series is not a a.p

hope it helps you

thanks you
