By pythagoras theorem,
By pythagoras theorem,
Proof with explanation:
We know that the sum of first 'n' terms of a Geometric progression is given by
where
a = first term of G.P
r is the common ratio
'n' is the number of terms
Thus the sum of 'n' terms is
Now the sum of first '2n' terms is
Now the sum of terms from to
term is
Thus the ratio becomes
