Q1 of 110 Page 48

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

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

i.e., if

)

Given: a₁ = 12, a₂ = 1,

Now,

And

Therefore,

Now, ∵ the ration is same,

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

0.004, 0.02, 0.1,….
