    The nth position in the sequence is the number in the nth term of the sequence.

    Explanation:

    Basically nth term is the expression itself. In mathematics nth term is expressed in the form of n which is actually the expression itself.

    The nth term corresponds to the value of n. If n = 3 and the expression is 2n, then the nth term would be 6 (2x3). All expressions given in the question may have their own nth term based on the value of n. Let's have a look at these examples:

    When n = 5,

    - 2n + 2 = 2 (5) + 2 = 12

    - 2n = 2 (5) = 10

    - 3n - 1 = 3 (5) - 1 = 14

    - 3n + 3 = 3 (5) + 3 = 18

    - 4n = 4 (5) = 20
