这是一个典型的无穷递归序列求和的问题,其中每一项都是两个相邻素数之比。我们可以编写一个Python程序来计算前10项的和。首先,我们需要生成一系列这样的分数,并找到它们对应的前10对连续的素数。下面是一个简单的实现:
```python
def is_prime(n):
if n <= 1:
return False
for i in range(2, int(n**0.5) + 1):
if n % i == 0:
return False
return True
def fibonacci_like_sum(n):
primes = [2] # Start with the first prime number
sum_of_terms = 0
count = 0
while count < n:
next_prime = primes[-1]
# Find the next consecutive prime
for num in range(primes[-1], primes[-1]*next_prime, next_prime): # Skip multiples of the current prime
if is_prime(num):
primes.append(num)
break
# Calculate the term and add it to the sum
term = primes[count+1] / primes[count]
sum_of_terms += term
count += 1
return sum_of_terms
# Calculate the sum of the first 10 terms
sum_10_terms = fibonacci_like_sum(10)
print(f"The sum of the first 10 terms is: {sum_10_terms}")
```
这个脚本会打印出前10项的和。请注意,由于涉及到大量的素数检查,实际运行时可能会比较慢。
