Question

Is the sequence geometric? Is so identify the common ratio 1/4, 3/15, 9/64, 27/256, 81/1024....

Answer 1

Hello.

Yes, it is geometric and the ratio is 3/4. You can tell because you can divide each one by the one before and you get 3/4. (3/16)/(1/4)=3/4, (9/64)/(3/16)=3/4, and so on.

Have a nice day
