Is this a sequence?

    1. The problem statement, all variables and given/known data
    I have a problem where I need to know if I can make a sequence for this data to the nth term. The first term, however, isn't common. Is there any way to somehow make it a sequence?
    At dose 1 y(1)=De^(0*12*k)/(1-e^(0*12*k))
    at dose 2 y(2)=D*e^(1*12*k)/(1-e^(12k)) + De^(0*12*k)
    at dose 3 y(3)=D*e^(2*12*k)/(1-e^(12k)) +De^(1*12k)+De^(0*12*k)
    so it should continue so that De^(12nk)+D(1+e^(1*12*k)+e^(2*12*k)+...+e^(nkt))
    Is there any way i can make it look somewhat like a sequence or an nth term equation?

    Well, of course, it is a sequence but you seem to be asking if you can write a formula for the "nth" value. If it is only the first term that is a problem, write y(1)= your first formula, then "if n> 1, y(n)= ".
