**jai**, Thursday, October 28, 2010 at 10:37amwhite: 3 9 27

black: 1 4 13

notice that for the white triangle,,

let n = number of terms,, if n=1 , white=3, if n=2, white=9, thus the pattern for white is

white = 3^n

for the black, notice that the next term would be the sum of previous values of both white and black,, for instance, if n=2, black=4 because 3 (number of white at n=1) plus 1 (number of black at n=1) is equal to 4,, at n=3, black = 13 because 9+4=13,, just follow this pattern until you reach n=15.

hope this helps. :)
