    What difficulty are you having? These problems ask you to give examples. Do you understand what they are asking?

    Let us agree that n\in\mathbb{Z}^+.

    For #1 let {A_n} = \left( {0,\tfrac{1}{n}} \right)

    For #2 let {A_n} = \left( { - \tfrac{1}{n},\tfrac{1}{n}} \right)

    I have thought the examples Plato wrote but I have difficulty in proving that they have the stated property.

    Thanks for the answers.
