Kann mir jemand die Aufgabenstellung erklären? Geben Sie die Glieder der Zahlenfolge (an) an ,die um weniger als 0,1 von 1 abweichen?

I know how to calculate epsilon

… you are calculated not ε, when it comes to the convergence of consequences, it is calculated for a given ε that n from which the sequences differ by less than ε from the (presumed) limit value. In your last question there was a value n > 3,16 for ε = 0.1. That means₄ all the following elements are less than 0.1 from 1.

Here is a small table (from “green deposited” the distance of the followers from 1 from your last question is smaller than ε – the smaller ε must be n so that this is the case)
