Best ResponseYou've already chosen the best response.0you can just plug in the sequence indices to each choice until you get one that matches. \(a_1=\dfrac{1}{3}\\a_2=\dfrac{1}{2}\\a_3=\dfrac{3}{5}\\....\)

Best ResponseYou've already chosen the best response.2r= 1/2  1/3 = 3/6  2/6 = 1/6 a (first in the sequence) = 1/3 nth term = a + r( n  1) = 1/3 + 1/6 ( n 1)

Best ResponseYou've already chosen the best response.2By the way, why don't you use the "dumbs way" ? Put 1 , 2, 3 ,4 the one which gives you the same numbers as the choices is the right one.
