Hey Mate⭐⭐⭐

Here's ur answer ⤵⤵⤵

♦Arithmetic progression => The series which is in the form a,a+d,a+2d,a+3d,.......... are called arithmetic progression.

In above options only option d) not follows this pattern so the series 0.2,0.22,0.222,0.2222,...... is not a arithmetic progression.

So the correct option is d)
