它的通项公式为:(1/√5)*{[(1+√5)/2]^n-[(1-√5)/2]^n}【√5表示根号5】
他的代码return1,是指序列从1开始,1,1,2,3,从0开始的话,改成if(k==0)return0;elseif(k==1)return1;elsereturnfib(k-1)+fib(k-2
*求斐波那契数列1,1,2,3,5,8,13,21,34,…的前30项的和.该数列从第3项开始每项等于前两项之和.3524577SETTALkOFFCLEAS=2F1=1F2=1I=2DOWHILEI

用矩阵加速[f(n+1)][11][f(n)]=[f(n)][10][f(n-1)]不停的迭代就行了递归求解,log(n)的programfibonacci;typematrix=array[1..2

只要函数对吧.如下:%Paradise1022functiony=Fibonacci(n)a(1)=1;a(2)=2;fori=3:na(i)=a(i-1)+a(i-2);end;y=a(n);测试结

解题思路:把路程看做工作量1,时间看做工作效率来解决问题解题过程:解1÷(1/12+1/18)=1÷(3/36+2/36)=1÷(5/36)=36/5(分钟)
写出1:第4个平方数;[答案:16]2:第5个斐波纳契数;[答案:5]3:第6个平方数;[答案:36]4:第7个三角数;[答案:28]5:第8个斐波纳契数.[答案:21]楼上的……,
斐波那契数列通项公式推导方法Fn+1=Fn+Fn-1两边加kFnFn+1+kFn=(k+1)Fn+Fn-1当k!=1时Fn+1+kFn=(k+1)(Fn+1/(k+1)Fn-1)令Yn=Fn+1+kF
解题思路:本题需仔细分析题意,结合图象,利用函数解析式即可解决问题.解题过程:答案见附件最终答案:略
