My friend was doing an analytical geometry problem and a shape appeared that I wanted to find the area of with my new knowledge of integrals. I found the area and i'm now working to find an equation for the nth area as the size of the shape changes for all integers. After doing the math I come to this sequence, (4/3), (32/3), (108/3). I stopped at the third solution because the math is a little time consuming and repetitive. Is there an equation that will represent the nth solution? Just hoping to get some help. Thanks.
