My teacher wants me to find the next three rows on this number triangle, but i can't find a pattern
1
1 1
2 1
1 2 1 1
1 1 1 2 2 1
3 1 2 2 1 1
PLEASE help me!
These are descriptive strings, each row describes the one above.
The last row tells us that the previous row was three 1's , followed by
two 2's, followed dy one 1.
So the next row is (1 3) (1 1) (2 2) (2 1) = 1 3 1 1 2 2 2 1
that is it tells us that the last row consisted of one 3, one 1, two 2's
followed by two 1's.
Please do the next two yourself.
