First Answer
an+1 = 1.1a.
The right side is not dependent on n . Hence the right side a constant independent of n. That means  an+1  is in equilibrium ste only, for all n.

If  you mean an+1 = 1.1an==>
a1 = 1.1a0
a2 =1.1(a1) = (1.1)2a0
|||ly,
an = (1.1)na . The an  according to the model grows large , without equilibrium state, for large n.

Let us have a poulation of 100 mice. Their population  values according to model  is as below.(Please read the fractions to nearest whole, as it is only a model)

Mice population of n+1st generation  an+1 = 1.1an
