- 8, 10, 18, 44, 124, x
1st differences: 2, 8, 26, 80, x - 124
2nd differences: 6, 18, 54, x - 204
From here, I see that:
6 = 6*1 = 6*(3^0)
18 = 6*3 = 6*(3^1)
54 = 6*9 = 6*(3^2)
So the next 2nd difference after 54 could be 6*(3^3) = 162.
That is, x - 204 = 162, so, x = 366. - 10 years agoHelpfull: Yes(15) No(0)

- 8 10 18 44 124 X
difference : 2 8 26 80 x-124
then, 6 18 54
6=6*(3^0)
18=6*(3^1)
54=6*(3^2)
then,
x-124=162
ans=366
