i.e. the sequence prize willbe : $20 , 2 x ($20) , 2² x ($20)x ....

That is its is an geometric progression with the common ratio r= 2,

Since the sum of n terms in GP is given by :-

So the total money will it hand out in prizes after 8 questions would be :

Hence, the total money it will hand out in prizes = $5100
