根據遞推關係，如何編程計算這個數列的前10項？

瀉藥，讓我們把題目寫出來，然後讓計算機算吧：

Prelude&> let s 1 = a 1; s n = s (n - 1) + a n ; a 1 = 1; a n = sqrt (s (n-1) ^ 2 + s (n-1) + 1);
Prelude&> map a [1..10]
[1.0,1.7320508075688772,3.3460652149512318,6.634878326370106,13.241345085141644,26.46851100630659,52.929935752185,105.85632878916633,211.71088627260133,423.42088689882064]


from math import sqrt

# n -- an, the amount of elements you need
def computation(n):
elements = [1]
_sum = 1 # a1
while len(elements) &< n: result = sqrt(_sum*_sum + _sum + 1) _sum += result elements.append(result) return elements computation(10)
