How did they get from line 1 in this picture to line 2
In relation to this proof
 L(k+1)/2J k+1-1 j-0 i=0 Fk+2 = Solution
The Pascal triangle and the aaray of numbers and indicated numbers in the triangle are Fibonacci numbers. The second line Fk+Fk+1=Fk+2 derived from the properties of Fibonacci numbers Fn-1+Fn=Fn+1
