Here, we need to specify the region of convergence (ROC) (ROC:0. 4, <Z<2), then only it's possible to say, it is stable or not.
Other wise its difficult.

Please explain the method to solve this question.

I think the question is incomplete .
Without ROC, it is difficult to define or at least the signal type i.e. causal/non-causal /anti-causal should have been mentioned.

The system is unstable. ROC doesn't include unit circle.

No, it is unstable.

Mix causal and anti-causal signal than it is stable.

Poles are the right side of the circle. So it is stable.

Since one pole magnitude lies outside the unit circle so system is unstable.
