  1. In all 3 questions you are using the same formula

    term(n) = a + (n-1)d

    1. term(101) = x-y + 100(2x+y-3)
    = x-y+200x + 100y - 300
    = 201x + 100y - 300

    2.
    a=2 , d=4
    2 + (n-1)(4) = 106
    4n-4 = 104
    4n = 108
    n = 27
    It is the 27th term

    3. give this one a try yourself
