Nth term sequence is n + 4 are the first three terms

A nth term is 85 - 5n are the first three terms of the sequence

17, 34, 51,

  1. first one is correct

    second:
    term(1) = 85 - 5(1) = 80
    term(2) = 85 - 5(2) = 75
    term(3) = .... = 70

    third:
    term(n) = 2n - 0.5
    term(1) = 2 - .5 = 1.5
    term(2) = 4 - .5 = 3.5
    term (3) = 6 - .5 = 5.5
