From1 Maths Fibonacci sequence

發問:

It is given that 89 and 144 are the 11th term and the 12th term of the Fibonacci Sequence respectively. Find the 13th term and the 14th term of the sequence. Use general term

最佳解答:

Fibonacci sequence 的下一項就是把之前的兩項相加。 用數學符號來表達,即是: (General Term) T(n) = T(n-2) + T(n-1) for n >= 3 with T(1) = T(2) = 1 即第 n 項 = 第 (n-2) 項 + 第 (n-1) 項 It is given that T(11) = 89 T(12) = 144 Therefore, T(13) = T(11) + T(12) = 89 + 144 = 233 T(14) = T(12) + T(13) = 144 + 233 = 377
