S=1+1/(1+1*2)+1/(1+2*2)+...+1/(1+2(n-1))可否写为S=∑(上标n,下标k=0)1/(1+2k)S=1+1/(1+1*2)+1/(1+2*2)+...+1/(1+2

S=1+1/(1+1*2)+1/(1+2*2)+...+1/(1+2(n-1))可否写为S=∑(上标n,下标k=0)1/(1+2k)
S=1+1/(1+1*2)+1/(1+2*2)+...+1/(1+2(n-1))可否写为S=∑(上标n,下标k=0)1/(1+2k)

S=1+1/(1+1*2)+1/(1+2*2)+...+1/(1+2(n-1))可否写为S=∑(上标n,下标k=0)1/(1+2k)
上标不对,应该是n-1
S=∑(上标n-1,下标k=0)1/(1+2k)
