Coding Assistance

Write a Python function to find the Fibonacci sequence up to n terms.

def fibonacci(n): if n <= 0: return [] elif n == 1: return a, b = 0, 1 seq = [a] for _ in range(n-1): seq.append(b) a, b = b, a + b return seq print(fibonacci(10)) # [0,1,1,2,3,5,8,13,21,34]

Multilingual Math

用中文解释并解决: 求解方程 2x + 3 = 7.

这是一个一元一次方程。解法：2x + 3 = 7 → 2x = 4 → x = 2。验证：22 + 3 = 7，正确。
