本文探讨了斐波那契数列中首个达到一千位数长度的项，并介绍了斐波那契数列的基本定义及其递推公式。通过解析数列特性，文章指出找到这一特定项的重要性。
The Fibonacci sequence is defined by the recurrence relation:
Fn = Fn-1 + Fn-2, where F1 = 1 and F2 = 1.
Hence the first 12 terms will be:
F1 = 1
F2 = 1
F3 = 2
F4 = 3
The 12th term, F12, is the first term to contain three digits.
What is the first term in the Fibonacci sequence to contain 1000 digits?
第一个长度为1000的斐波纳契序列的位置为？
