Answer:
Yes they are in A.P.
common difference is -2.0
Three more terms are -9.2, -11.2 and -13.2
Step-by-step explanation:
-3.2-(-1.2) = -2.0
-5.2-(-3.2) = -2.0
-7.2-(-5.3) = -2.0
Since their common difference (d) is -2.0 ,therefore they are in A.P.
Three more terms are:
-7.2+(-2.0) = -9.2
-9.2+(-2.0) = -11.2
-11.2+(-2.0) = -13.2
