According to the pattern, the number of kernel of corn is double every day, so we can conclude that the number of kernel of corn oN as a function of the days x is given by:


N(x)=2^(x-1)

For x = 21:


N(21)=2^(21-1)=2^(20)=1048576

Since each kernel corn weighs 0.07, the total weight is given by:


\begin{gathered} Tw=0.07\cdot1048576 \\ Tw=73400.32g \end{gathered}
