The easiest way is to use the Basic Typesetting palette. There you will find
a template for the situation you describe. If the palette doesn't show up on
starting Mathematica, use File | Palettes | 5 BasicTypesetting. Now, bear in
mind that whereas the exponent "2" is understood as such, the subscript i
has no meaning by itself and if you want to use it to denote the i-th partof
the list x you must previously define it to mean that (see The Book,
2.8.15). The x with subscript i obtained with the palette is equivalent to
Subscript[x, i]. Then for example, define

In[1]:=
Subscript[x_,  i_] := x[[i]]

In[2]:=
x = {1, 3, 8}; a = {4, 5, 6};

In[3]:=
Subscript[x, 1]
Out[3]=
1
In[4]:=
Subscript[a, 2]
Out[4]=
5
