Best ResponseYou've already chosen the best response.1hint: the ratio between one term and its preceding term is constant, and we can write this: \[\left( {1/16} \right):\left( {  1/8} \right) = \left( {  1/8} \right):\left( {1/4} \right) = \left( {1/4} \right):\left( {  1/2} \right) = ...?\]

Best ResponseYou've already chosen the best response.1no, it is an arithmetic sequence, since the difference between one term and its preceding term is constant: 0(5)= 50= 105=...?
