🔢 数字找规律Number Pattern
在线数字找规律：观察一串数字，找出隐藏的规律，从四个选项中选出下一个数。题型包括等差、等比、平方数、立方数、质数、斐波那契式、差数递增、两组交错等。每轮 10 题，分简单、中等、困难三档，答完会讲解规律，适合锻炼逻辑推理和数感。Number Pattern online: look at a sequence, work out the hidden rule and pick the next number from four choices. Rules include arithmetic and geometric steps, squares, cubes, primes, Fibonacci-style sums, growing gaps and two interleaved sequences. Ten questions per round at three levels, with the rule explained after each answer — good practice for logical reasoning and number sense.

「数字找规律」怎么玩？How do I play Number Pattern?
先看相邻两个数的差：差相同是等差；差在变化就再看差的差。也可以试试相邻两数的比（是否每次乘同一个数）、是否是平方/立方/质数，或者单数位和双数位是不是各自一组规律。每题 10 分，10 题满分 100。Start with the gaps between neighbours: equal gaps mean an arithmetic step; changing gaps — look at the gaps of the gaps. Also try ratios (multiplying by the same number), squares, cubes or primes, or whether odd and even positions follow two separate rules. Each question is worth 10, so 100 is a perfect round.
会不会有多种规律都说得通？Could more than one rule fit?
题目由固定规则生成，选项中只有一个符合该规则；答完后会显示所用的规律。Each question comes from one rule and only one option fits it; the rule is shown after you answer.
“困难”有哪些题型？What is in Hard?
两组交错数列、立方数、质数、n×(n+1)、交替“乘 2 / 加 k”等。Interleaved sequences, cubes, primes, n×(n+1), alternating “×2 / +k” and more.
