          stages    dies                          born

          I               1                                2

          II              2^{1}           4 = 2^{2}

          III              2^{2}          8 = 2^{3}

At  n^{th} =  2^{n}    2^{n+1}

By the geometric series formula:

 1+a^{1}+ a^{2}+ a^{3}...+ a^{n}=\frac{a^{n+1} }{a^-1} }

so,  1+2^{1}+ 2^{2}+ 2^{3}...+ 2^{n}=\frac{2^{n+1} }{2^-1} }

Thus, total amoeba died = 2^{n+1}-1

        total amoeba died+1 = 2^{n+1} (born).... hence prooved
