Given series is
\small 0.2,0.22,0.222,0.2222,...
Now,
the first term to this series is = 0.2
Now,
a_1 = 0.2 \ \ and \ \ a_2 = 0.22 \ \ and \ \ a_3 = 0.222 \ \ and \ \ a_4 = 0.2222
a_2-a_1 = 0.22-0.2=0.02
a_3-a_2 = 0.222-0.22=0.002

We can clearly see that the difference between terms are not equal  
Hence, given series is not an AP
