    P_0 is the no of cells in the petri dish on day 0
    p is the fraction of cells which survive and split into 2
    1-p is then the fraction of cells which die
    each cell contributes on average 2d+0x(1-d) cell to the next gen
    but why 0x? surely some cells would die rather than none?


    so then

    p_{n+1} =(2d+0\cdot (1-d))\cdot P_n

    You talk about p, but your equation has d's, and you talk about x, but there is none - trying to confuse us?

    It's not saying none die, only that they contribute nothing to the next day's count.

    The next day consists of twice the number that split, 2dP_n, and none of the ones that don't split (as they die), 0(1-d)P_n. The second term is really completely redundant.
