Answer:
G.P. means the ratio of successive terms will be equal.
for example -
if terms of a G.P. are
a,b,c,d. then
b/a= c/b = d/c
In
1) -32/64= -1/2
and 16/(-32)= -1/2
as the ratio is same , so this is a G.P
2) 6/3= 2
12/6=2
as the ratio is same , so this is a G.P
3) 32/64= 1/2
8/32= 1/4
as the ratio is not same, so it is not a G.P
4) 2/1=2
3/2=1.5
4/3= 1.33
as the ratios are not equal , so it is not a G.P
This is the answer.
Hope it helps !
