I remember when you couldn't post pictures. So I had to post URLS to websites with the picture in it.
+1009 See the pattern:
For 1)
n to the second row remains in a 1:5 ratio-
1x5 = 5
2x5=10
etc.
Thus, 4x5 = 20.
The second one is n+2 = bottom layer.
You can solve for the rest :)
let me know if you need any other help!
