1 1 1

, , ,.....

64 32 8

4) 1,2,3,4,…​

Answer 1

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 !
