anonymous · Answer

8-1 = 7 ,16-8 =8 ,25-16 = 9,, so x -25 = n+1
you should be able to see the difference in pattern by 7 then 8 then 9 then so it's n +1

marigirl · Answer

yes, with a difference of 10 then?
1         8          16            25           35
    7            8              9           10          Difference
