B. 1707

2
2 +(5) = 7
7 +(5*4) = 27 (where 5 is difference between 1st and 2nd term)
27 +(20*4) = 107 (where 20 is difference between 2nd and 3rd term)
107 +(80*4) = 427 (where 80 is difference between 3rd and 4th term)
427 +(320*4)= 1707(where 320 is difference between 4th and 5th term)

Final sequence = 2, 7, 27, 107, 427,1707
