(Greetings from The On-Line Encyclopedia of Integer Sequences!)
A099731 This table shows the coefficients of sum formulas of n-th Fibonacci numbers (A000045). The k-th row (k>=1) contains T(i,k) for i=1 to k, where k=[2*n+1+(-1)^(n-1)]/4 and T(i,k) satisfies F(n)= Sum_{i=1..k} T(i,k) * n^(k-i)/(k-1)!. 15

EXAMPLE

F(13)=233; substituting n=13 in the formula of the k-th row we obtain k=7 and the coefficients

T(i,7) will be the following: 1,-51,1135,-13665,93544,-342324,523440,

=> F(13) = [13^6-51*13^5+1135*13^4-13665*13^3+93544*13^2-342324*13+523440]/6! = 233.
