Let us consider n=1
then we get (2n+1)= 2*1+1=3
let us consider those 3 terms be 1,2,3
sum of the odd terms 1+3=4
sum of the even terrms =2
Now the ratio of odd terms to even terms is 4:2=2:1
which satisfy the condition (n+1):1=(1+1):1=2:1
Hence proved
ok i am studying 12th
I'm 10th
I just passed out 10th
Hmmmm
