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
