The figure number and the number of tiles are related by the number the formula
t = (f + 2)^2
The number of tiles (t) equals the figure number plus 2 the result of that squared.
For example for f =1
the number of tiles is t = (n + 2) ^2 = (1 + 2)^2 = 3^2 = 9
For f = 2
The number of tiles = (n+2)^2 = (2 + 2)^2 = 4^2 = 16
For f = 3
The number of tiles = (n + 2)^2 = (3 + 2)^2 =5^2 = 25
We can be fairly confident in the formula. So what about figure 100
t = (n + 2)^2 = 102^2 = 10404 tiles.
Your next problem is figure out what this will look like.
You are going to have to do a little reading as you draw this on a piece of paper.
Go back to figure 1. There is a square in the middle of the drawing. The square consists of 4 tiles. Draw them on a piece of paper. I can't reproduce them, but it looks like every drawing has a square with (n + 1)^2 tiles in it.
Look at figure 2. There is a square in the middle of the drawing. The figure number plus 1 all squared = the number of tiles in that square. t = (f + 1)^2. You should be able to see 9 squares in that central square.
Three will give you 16 squares in the middle square.
===========================================
Now there are arms coming off the square. Again each arm is related to the figure number.
In figure 1 the arm length is 2 tiles. It suggests 2*f is the number of tiles in both arms together.
Figure 2 has 3 tiles in each arm. That means that the total number of tiles used for 1 arm (f + 1) = (2 + 1) = 3
Figure 3 has 4 tiles in each arm. Total 8.
===================
Finally all figures have 1 tile sitting on top of everything else. No more than 1 and no less than 1. Just 1.
===============================
Now we are ready to talk about figure 100.
The square in the middle was determined to be (f + 1)^2 = 101^2 = 10201
The arms were determined to be t = 2 *( f + 1) = 2 * 101 = . . . . .. . . . . .202
And there is one more square that every figure has . . . . . . . . . . . . . . . ..1
Total . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .10404
Just what we got before. If you need more, leave a note about what you need, in detail.
