Solution : (i)We know that a list of numbers a1
, a2
, a3
, .....an
..... is called a GP if each term is
non zero and 32
Here all the terms are non zero. Further
So, the given list of number forms a GP with the common ratio 2.
(ii) All the terms are non zero.
2
1
32 1
So, the given list of numbers form a GP with common ratio
1
2
-
.
(iii) All the terms are non zero.
So, the given list of numbers does not form GP.
So, the given list of numbers does not form GP.
