Hello, IndyMedicGuy!

There is typo in #1 . . .

#1. This is a sequence of numbers 0-15.

There are three missing numbers 0, 7, and 9.

I have to figure out in what position these numbers go in the sequence and why.

Here is the sequence: .$\displaystyle 8,\;11,\;15,\;5,\;4,\;14,\;\_\_,\;1,\; \_\_,\;6,\;10,\;13,\;3,\;{\color{blue}12,\;2},\;\_ \_$

Write out the English words for the numbers: . $\displaystyle \begin{array}{c}\text{eight}\\ \text{fifteen}\\ \text{five}\\ \text{four}\\ \text{fourteen} \\ \_\_ \\ \text{one} \\ \_\_ \\ \text{six}\\ \text{ten} \\ \vdots \end{array}$

Do you see a pattern?

2. Find the relationship between each number and its corresponding shape. Ever play tic-tac-toe? Code:
