However, a Fibonacci sequence can be created with any two starting num. bers. Fibonacci sequences appear regularly in nature. For example, the shell of the chambered nautilus $($see Figure P$9\mathrm{.}6)$ grows in accordance with $a_a$ Fibonacci sequence.

Prompt the user to enter the first two numbers in a Fibonacci sequence, and the total number of elements requested for the sequence. Find the sequence and store it in an array by using a for loop. Now plot your results on a polarplot graph. Use the element number for the angle, and the value of the element in the sequence for the radius.

$9\mathrm{.}7$ Repeat the preceding problem, this time using a while loop.
