Q1 of 110 Page 48

Find out which of the following sequences are geometric sequences. For those geometric sequences, find the common ratio.

0.12, 0.24, 0.48,….

(Note: Sequences are in G.P. if they have common ratios


i.e., if


)


Given: a1 = 0.12, a2 = 0.24, a3 = 0.48


Now,




And,




Therefore,



Now, ∵ the ration is same,


⇒ 0.12, 0.24, 0.48, … is a G.P with common ratio = 2
