AP的条款总和

Question

我写了一个代码来显示AP的编号，与输入的编号

的条件相关联

P = int(input())
R = int(input())
Q = int(input())
S = 0
Cont = 0
while Cont<=Q:
 print("Termo",Cont,"da PA = ",P)
 P = P+R
 Cont = Cont+1

它工作正常，但在这种情况下，我如何总结AP的所有条款？

Answer 1

在循环中添加计算的术语。

P = int(input())
R = int(input())
Q = int(input())
S = 0
Cont = 0
while Cont<=Q:
 print("Termo",Cont,"da PA = ",P)
 S = S + P
 P = P+R
 Cont = Cont+1

print("Sum:",S)
