Linq Select from an array where element indexes satisfy a criteria

[Arjang Assadi]

Given an array, how can a subset of it be selected based on
restriction on the elements index?

e.g. given the array numbers [1,2,2,3,3,5,6];

from number in numbers where ( number is even indexed ) select number

or

from number in numbers where ( number index is greater than 2 ) select number
