菲波那契数列指的是这样一个数列：1,1,2,3,5,8,13,21……这个数列从第三项开始,每一项都等于前两项之和.它的通项公式为：(1/√5)*{[(1+√5)/2]^n-[(1-√5)/2]^n}

你写的有问题,斐波那契（Fibonacci）数列指的是这样一个数列：f(1)=1,f(2)=1,f(3)=f(1)+f(2)=2,f(4)=f(2)+f(3)=3,…这个数列从第三项开始,每一项都等于

你的意思是：第1组1,2；第2组3,5,8,第3组,13,21,34,55；计算2014所在的那一组?再问：是的。编程......再答：对的话多个点分clccleara=[];a(1)=1;a(2)=
